Protestantism is the second largest form of Christianity with collectively between 800 million and more than 900 million adherents worldwide or nearly 40% of all Christians. It originated with the 16th century Reformation, a movement against what its followers perceived to be errors in the Roman Catholic Church. Protestants reject the Roman Catholic doctrine of papal supremacy and sacraments, but disagree among themselves regarding the real presence of Christ in the Eucharist, they emphasize the priesthood of all believers, justification by faith alone rather than by good works, the highest authority of the Bible alone in faith and morals. The "five solae" summarise basic theological differences in opposition to the Roman Catholic Church. Protestantism is popularly considered to have begun in Germany in 1517 when Martin Luther published his Ninety-five Theses as a reaction against abuses in the sale of indulgences by the Roman Catholic Church, which purported to offer remission of sin to their purchasers.
However, the term derives from the letter of protestation from German Lutheran princes in 1529 against an edict of the Diet of Speyer condemning the teachings of Martin Luther as heretical. Although there were earlier breaks and attempts to reform the Roman Catholic Church—notably by Peter Waldo, John Wycliffe, Jan Hus—only Luther succeeded in sparking a wider and modern movement. In the 16th century, Lutheranism spread from Germany into Denmark, Sweden, Latvia and Iceland. Reformed denominations spread in Germany, the Netherlands, Scotland and France by reformers such as John Calvin, Huldrych Zwingli, John Knox; the political separation of the Church of England from the pope under King Henry VIII began Anglicanism, bringing England and Wales into this broad Reformation movement. Protestants have developed their own culture, with major contributions in education, the humanities and sciences, the political and social order, the economy and the arts, many other fields. Protestantism is diverse, being more divided theologically and ecclesiastically than either the Roman Catholic Church, the Eastern Orthodox Church, or Oriental Orthodoxy.
Without structural unity or central human authority, Protestants developed the concept of an invisible church, in contrast to the Roman Catholic view of the Catholic Church as the visible one true Church founded by Jesus Christ. Some denominations do have a worldwide scope and distribution of membership, while others are confined to a single country. A majority of Protestants are members of a handful of Protestant denominational families: Adventists, Anglicans, Reformed, Lutherans and Pentecostals. Nondenominational, charismatic and other churches are on the rise, constitute a significant part of Protestant Christianity. Proponents of the branch theory consider Protestantism one of the three major divisions of Christendom, together with the Roman Catholic Church and Orthodoxy. Six princes of the Holy Roman Empire and rulers of fourteen Imperial Free Cities, who issued a protest against the edict of the Diet of Speyer, were the first individuals to be called Protestants; the edict reversed concessions made to the Lutherans with the approval of Holy Roman Emperor Charles V three years earlier.
The term protestant, though purely political in nature acquired a broader sense, referring to a member of any Western church which subscribed to the main Protestant principles. However, it is misused to mean any church outside the Roman and Eastern Orthodox communions. Protestantism as a general term is now used in contradistinction to the other major Christian traditions, i.e. Roman Catholicism and Orthodoxy. During the Reformation, the term protestant was hardly used outside of German politics. People who were involved in the religious movement used the word evangelical. For further details, see the section below. Protestant became a general term, meaning any adherent of the Reformation in the German-speaking area, it was somewhat taken up by Lutherans though Martin Luther himself insisted on Christian or evangelical as the only acceptable names for individuals who professed Christ. French and Swiss Protestants instead preferred the word reformed, which became a popular and alternative name for Calvinists.
The word evangelical, which refers to the gospel, was used for those involved in the religious movement in the German-speaking area beginning in 1517. Nowadays, evangelical is still preferred among some of the historical Protestant denominations in the Lutheran and United Protestant traditions in Europe, those with strong ties to them. Above all the term is used by Protestant bodies in the German-speaking area, such as the Evangelical Church in Germany. In continental Europe, an Evangelical is either a Calvinist, or a United Protestant; the German word evangelisch means Protestant, is different from the German evangelikal, which refers to churches shaped by Evangelicalism. The English word evangelical refers to evangelical Protestant churches, therefore to a certain part of Protestantism rather than to Protestantism as a whole; the English word traces its roots back to the Puritans in England, where Evangelicalism originated, was brought to the United States. Martin Luther always disliked the term Lutheran, preferring the term evangelical, derived from euangelion, a Greek word meaning "good news", i.e. "gospel".

Christianity is an Abrahamic religion based on the life and teachings of Jesus of Nazareth, as described in the New Testament. Its adherents, known as Christians, believe that Jesus Christ is the Son of God and savior of all people, whose coming as the Messiah was prophesied in the Old Testament. Depending on the specific denomination of Christianity, practices may include baptism, prayer, confirmation, burial rites, marriage rites and the religious education of children. Most denominations hold regular group worship services. Christianity developed during the 1st century CE as a Jewish Christian sect of Second Temple Judaism, it soon attracted Gentile God-fearers, which lead to a departure from Jewish customs, the establishment of Christianity as an independent religion. During the first centuries of its existence Christianity spread throughout the Roman Empire, to Ethiopia and some parts of Asia. Constantine the Great decriminalized it via the Edict of Milan; the First Council of Nicaea established a uniform set of beliefs across the Roman Empire.
By 380, the Roman Empire designated Christianity as the state religion. The period of the first seven ecumenical councils is sometimes referred to as the Great Church, the united full communion of the Roman Catholic Church, Eastern Orthodox Church, Oriental Orthodoxy, before their schisms. Oriental Orthodoxy split after the Council of Chalcedon over differences in Christology; the Eastern Orthodox Church and the Catholic Church separated in the East–West Schism over the authority of the Pope. In 1521, Protestants split from the Catholic Church in the Protestant Reformation over Papal primacy, the nature of salvation, other ecclesiological and theological disputes. Following the Age of Discovery, Christianity was spread into the Americas, sub-Saharan Africa, the rest of the world via missionary work and colonization. There are 2.3 billion Christians in the world, or 31.4% of the global population. Today, the four largest branches of Christianity are the Catholic Church, the Eastern Orthodox Church and Oriental Orthodoxy.
Christianity and Christian ethics have played a prominent role in the development of Western civilization around Europe during late antiquity and the Middle Ages. In the New Testament, the names by which the disciples were known among themselves were "brethren", "the faithful", "elect", "saints" and "believers". Early Jewish Christians referred to themselves as'The Way' coming from Isaiah 40:3, "prepare the way of the Lord." According to Acts 11:26, the term "Christian" was first used in reference to Jesus's disciples in the city of Antioch, meaning "followers of Christ," by the non-Jewish inhabitants of Antioch. The earliest recorded use of the term "Christianity" was by Ignatius of Antioch, in around 100 AD. While Christians worldwide share basic convcitions, there are differences of interpretations and opinions of the Bible and sacred traditions on which Christianity is based. Concise doctrinal statements or confessions of religious beliefs are known as creeds, they began as baptismal formulae and were expanded during the Christological controversies of the 4th and 5th centuries to become statements of faith.
The Apostles' Creed is the most accepted statement of the articles of Christian faith. It is used by a number of Christian denominations for both liturgical and catechetical purposes, most visibly by liturgical churches of Western Christian tradition, including the Latin Church of the Catholic Church, Lutheranism and Western Rite Orthodoxy, it is used by Presbyterians and Congregationalists. This particular creed was developed between the 9th centuries, its central doctrines are those of God the Creator. Each of the doctrines found in this creed can be traced to statements current in the apostolic period; the creed was used as a summary of Christian doctrine for baptismal candidates in the churches of Rome. Its main points include: Belief in God the Father, Jesus Christ as the Son of God, the Holy Spirit The death, descent into hell and ascension of Christ The holiness of the Church and the communion of saints Christ's second coming, the Day of Judgement and salvation of the faithful; the Nicene Creed was formulated in response to Arianism, at the Councils of Nicaea and Constantinople in 325 and 381 and ratified as the universal creed of Christendom by the First Council of Ephesus in 431.
The Chalcedonian Definition, or Creed of Chalcedon, developed at the Council of Chalcedon in 451, though rejected by the Oriental Orthodox churches, taught Christ "to be acknowledged in two natures, unchangeably, inseparably": one divine and one human, that both natures, while perfect in themselves, are also united into one person. The Athanasian Creed, received in the Western Church as having the same status as the Nicene and Chalcedonian, says: "We worship one God in Trinity, Trinity in Unity. Many evangelical Protestants reject creeds as definitive statements of faith while agreeing with some or all of the substance of the creeds. Most Baptists do not use creeds "in that they have not sought to establish binding
Luapula Province is one of Zambia's ten provinces located in the northern part of the country. Luapula Province is named after the Luapula River and its capital is Mansa; as per the 2010 Zambian census, the Province had a population of 991,927, which accounted for 7.57 per cent of the total Zambian population. The province has international border along Democratic Republic of the Congo and domestically extends along the northern and eastern banks of the Luapula river from Lake Bangweulu to Lake Mweru; the province is inhabited by Bemba, who are the major tribe in the country. Bemba is the most spoken language in the province; the major economic activity is fishing, with sweet potato being the major crop. Mutukumbo festival is the most important festival celebrated. Lumangwe Falls, Mumbuluma Falls, Mumbotuta Waterfalls, Kundabwika Waterfalls and Chilongo Waterfalls are the major water falls; the chief artery of the province is the Samfya-Mansa-Mwansabombwe-Nchelenge highway known informally as the Zambia Way.
The province is bordered through Lake Mweru and to its north by DR Congo. Around 80.5 per cent of the population of Luapula is accounted as poor in 2010 census, making it the poorest of all provinces in Zambia. It has eight major attractions of the country among its waterfalls and cultural heritage. Major mineral deposits found in the province are manganese, lime and precious metals. In the 19th century, the valley was dominated by the Kingdom of Lunda of Mwata Kazembe; the boundaries of the province between Zambia and DR Congo were disputed for many years, running from an 1894 treaty into the late 1960s. The province has a long history of opposing colonial rule through militancy. From the 1950s, there were revolutionary groups that supported the Anti Federationist African National Congress. Post independence, the province was the base for the United National Independence Party militants. Laupula has constant migration of labour from DR Congo and from nearby Copperbelt Province. During the 1980s, the President Kenneth Kaunda appointed traditional Chiefs of the region as District Governors or members of the powerful UNIP central committee.
The practice was seen similar to colonial rule. Mwata Kazambe was appointed the District Governor for the province by the President during the 1980s. Frederick Chiluba, the leader of Movement for Multi-Party Democracy, who went on to become the President of Zambia in 1991, obtained majority mandate during the 1991 elections; the province was the least affected among all areas in the country during the 1991 famine. Agriculture suffered in the region on account of removal of agricultural subsidies and rural credit schemes during the 1990s; the province is bordered through Lake Mweru and to its north by DR Congo. The Congo Pedicle is located between the province and the industrial and commercial heartland of the Copperbelt; the issues in transportation was resolved with the construction of the Luapula Bridge and the Samfya-Serenje road, being further alleviated by the construction of the Chembe Bridge. The capital of the province is Mansa, the headquarters of Mansa district; the province borders along DR Congo and it extends along the northern and eastern banks of the river from Lake Bangweulu to Lake Mweru, including waters and islands of those lakes.
Congo Pedicle, the southeast salient of the Katanga Province of the DR Congo, which sticks into neighbouring Zambia, divides it into two lobes. It is bordered by Northern Province on the eastern side and Central Province on the southeastern side; the major towns in the province include Samfya, Mansa and Mwamsombwe. Around 40 per cent of Luapula is covered with water and there are a number of rivers and lakes, it has eight attractions in waterfalls and cultural heritage. Major mineral deposits found in the province are manganese, lime and precious metals; as per the 2010 Zambian census, Luapula Province had a population of 991,927 which accounted for 7.57 per cent of the total Zambian population of 13,092,666. There were 488,589 males and 503,338 females, making the sex ratio to 1,030 for every 1,000 males, compared to the national average of 1,028; the literacy rate stood at 62.60 per cent against a national average of 70.2 per cent. The rural population constituted 80.39 per cent. The total area of the province was 50,567 km2 and the population density was 19.60 per km2.
The population density during 2000 Zambian census stood at 19.60. The decadal population growth of the province was 2.50 per cent. The median age in the province at the time of marriage was 20.3. The average household size was 4.9, with the families headed by females being 4.0 and 5.4 for families headed by men. The total eligible voters in the province was 65.40 per cent. The unemployment rate of the province was 7.70 per cent. The total fertility rate was 7.3, complete birth rate was 6.5, crude birth rate was 39.0, child women population at birth was 835, general fertility rate was 172, gross reproduction rate was 2.7 and net reproduction rate was 1.8. The total labour force constituted 58.60 per cent of the total population. Out of the labour force, 66.2 per cent were 51.7 per cent women. The annual growth rate of labour force was 1.9 per cent. Bemba was the most spoken language with 71.30 per cent speaking it. Albinism is a condition where the victims do not have any pigment in hair or eyes; the total population in the province with the condition stood at 2,278.
The life expectancy at birth stood at 45 compared to the national average of 51. Luapula is one of the poorest provinces in Zambia with 80.5 per cent of the popu
In biology, a population is all the organisms of the same group or species, which live in a particular geographical area, have the capability of interbreeding. The area of a sexual population is the area where inter-breeding is possible between any pair within the area, where the probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas. In sociology, population refers to a collection of humans. Demography is a social science. Population in simpler terms is the number of people in a city or town, country or world. In population genetics a sex population is a set of organisms in which any pair of members can breed together; this means that they can exchange gametes to produce normally-fertile offspring, such a breeding group is known therefore as a Gamo deme. This implies that all members belong to the same species. If the Gamo deme is large, all gene alleles are uniformly distributed by the gametes within it, the Gamo deme is said to be panmictic.
Under this state, allele frequencies can be converted to genotype frequencies by expanding an appropriate quadratic equation, as shown by Sir Ronald Fisher in his establishment of quantitative genetics. This occurs in Nature: localization of gamete exchange – through dispersal limitations, preferential mating, cataclysm, or other cause – may lead to small actual Gamo demes which exchange gametes reasonably uniformly within themselves but are separated from their neighboring Gamo demes. However, there may be low frequencies of exchange with these neighbors; this may be viewed as the breaking up of a large sexual population into smaller overlapping sexual populations. This failure of panmixia leads to two important changes in overall population structure: the component Gamo demos vary in their allele frequencies when compared with each other and with the theoretical panmictic original; the overall rise in homozygosity is quantified by the inbreeding coefficient. Note that all homozygotes are increased in frequency – both the deleterious and the desirable.
The mean phenotype of the Gamo demes collection is lower than that of the panmictic original –, known as inbreeding depression. It is most important to note, that some dispersion lines will be superior to the panmictic original, while some will be about the same, some will be inferior; the probabilities of each can be estimated from those binomial equations. In plant and animal breeding, procedures have been developed which deliberately utilize the effects of dispersion, it can be shown that dispersion-assisted selection leads to the greatest genetic advance, is much more powerful than selection acting without attendant dispersion. This is so for both autogamous Gamo demes. In ecology, the population of a certain species in a certain area can be estimated using the Lincoln Index. According to the United States Census Bureau the world's population was about 7.55 billion in 2019 and that the 7 billion number was surpassed on 12 March 2012. According to a separate estimate by the United Nations, Earth’s population exceeded seven billion in October 2011, a milestone that offers unprecedented challenges and opportunities to all of humanity, according to UNFPA, the United Nations Population Fund.
According to papers published by the United States Census Bureau, the world population hit 6.5 billion on 24 February 2006. The United Nations Population Fund designated 12 October 1999 as the approximate day on which world population reached 6 billion; this was about 12 years after world population reached 5 billion in 1987, 6 years after world population reached 5.5 billion in 1993. The population of countries such as Nigeria, is not known to the nearest million, so there is a considerable margin of error in such estimates. Researcher Carl Haub calculated that a total of over 100 billion people have been born in the last 2000 years. Population growth increased as the Industrial Revolution gathered pace from 1700 onwards; the last 50 years have seen a yet more rapid increase in the rate of population growth due to medical advances and substantial increases in agricultural productivity beginning in the 1960s, made by the Green Revolution. In 2017 the United Nations Population Division projected that the world's population will reach about 9.8 billion in 2050 and 11.2 billion in 2100.
In the future, the world's population is expected to peak, after which it will decline due to economic reasons, health concerns, land exhaustion and environmental hazards. According to one report, it is likely that the world's population will stop growing before the end of the 21st century. Further, there is some likelihood that population will decline before 2100. Population has declined in the last decade or two in Eastern Europe, the Baltics and in the Commonwealth of Independent States; the population pattern of less-developed regions of the world in recent years has been marked by increasing birth rates. These followed an earlier sharp reduction in death rates; this transition from high birth and death rates to low birth
Population density is a measurement of population per unit area or unit volume. It is applied to living organisms, most of the time to humans, it is a key geographical term. In simple terms population density refers to the number of people living in an area per kilometer square. Population density is population divided by total land water volume, as appropriate. Low densities may lead to further reduced fertility; this is called the Allee effect after the scientist. Examples of the causes in low population densities include: Increased problems with locating sexual mates Increased inbreeding For humans, population density is the number of people per unit of area quoted per square kilometer or square mile; this may be calculated for a county, country, another territory or the entire world. The world's population is around 7,500,000,000 and Earth's total area is 510,000,000 square kilometers. Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2. If only the Earth's land area of 150,000,000 km2 is taken into account human population density is 50 per km2.
This includes all continental and island land area, including Antarctica. If Antarctica is excluded population density rises to over 55 people per km2. However, over half of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states and dependencies; these territories have a small area and a high urbanization level, with an economically specialized city population drawing on rural resources outside the area, illustrating the difference between high population density and overpopulation The potential to maintain the agricultural aspects of deserts is limited as there is not enough precipitation to support a sustainable land. The population in these areas are low. Therefore, cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo and Lagos in Africa fall into this category. City population and area are, however dependent on the definition of "urban area" used: densities are invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, the surrounding suburbs excluded. In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet per person, would occupy a space a little larger than Delaware's land area; the Gaza Strip has a population density of 5,046 pop/km.
Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area. Arithmetic density: The total number of people / area of land Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources Demography Human geography Idealized population Optimum population Population genetics Population health Population momentum Population pyramid Rural transport problem Small population size Distance sampling List of population concern organizations List of countries by population density List of cities by population density List of city districts by population density List of English districts by population density List of European cities proper by population density List of United States cities by population density List of islands by population density List of U.

In economics, geography and sociology, the dependency ratio is an age-population ratio of those not in the labor force and those in the labor force. It is used to measure the pressure on the productive population. Consideration of the dependency ratio is essential for governments, bankers, industry and all other major economic segments which can benefit from understanding the impacts of changes in population structure. A low dependency ratio means that there sufficient people working who can support the dependent population. A lower ratio could allow for better health care for citizens. A higher ratio indicates more financial stress on working people. While the strategies of increasing fertility and of allowing immigration of younger working age people have been formulas for lowering dependency ratios, future job reductions through automation may impact the effectiveness of those strategies. In published international statistics, the dependent part includes those under the age of 15 and over the age of 64.
The productive part makes up the population in between, ages 15 – 64. It is expressed as a percentage: D e p e n d e n c y r a t i o = + n u m b e r o f p e o p l e a g e d 15 t o 64 × 100 \times 100} As the ratio increases there may be an increased burden on the productive part of the population to maintain the upbringing and pensions of the economically dependent; this results in direct impacts on financial expenditures on things like social security, as well as many indirect consequences. The dependency ratio can be decomposed into the child dependency ratio and the aged dependency ratio: C h i l d d e p e n d e n c y r a t i o = n u m b e r o f p e o p l e a g e d 0 t o 14 n u m b e r o f p e o p l e a g e d 15 t o 64 × 100 A g e d d e p e n d e n c y r a t i o = n u m b e r o f p e o p l e a g e d 65 a n d o v e r n u m b e r o f p e o p l e a g e d 15 t o 64 × 100 Below is a table constructed from data provided by the UN Population Division, it show
The public domain consists of all the creative works to which no exclusive intellectual property rights apply. Those rights may have been forfeited, expressly waived, or may be inapplicable; the works of William Shakespeare and Beethoven, most early silent films, are in the public domain either by virtue of their having been created before copyright existed, or by their copyright term having expired. Some works are not covered by copyright, are therefore in the public domain—among them the formulae of Newtonian physics, cooking recipes, all computer software created prior to 1974. Other works are dedicated by their authors to the public domain; the term public domain is not applied to situations where the creator of a work retains residual rights, in which case use of the work is referred to as "under license" or "with permission". As rights vary by country and jurisdiction, a work may be subject to rights in one country and be in the public domain in another; some rights depend on registrations on a country-by-country basis, the absence of registration in a particular country, if required, gives rise to public-domain status for a work in that country.
The term public domain may be interchangeably used with other imprecise or undefined terms such as the "public sphere" or "commons", including concepts such as the "commons of the mind", the "intellectual commons", the "information commons". Although the term "domain" did not come into use until the mid-18th century, the concept "can be traced back to the ancient Roman Law, as a preset system included in the property right system." The Romans had a large proprietary rights system where they defined "many things that cannot be owned" as res nullius, res communes, res publicae and res universitatis. The term res nullius was defined as things not yet appropriated; the term res communes was defined as "things that could be enjoyed by mankind, such as air and ocean." The term res publicae referred to things that were shared by all citizens, the term res universitatis meant things that were owned by the municipalities of Rome. When looking at it from a historical perspective, one could say the construction of the idea of "public domain" sprouted from the concepts of res communes, res publicae, res universitatis in early Roman law.
When the first early copyright law was first established in Britain with the Statute of Anne in 1710, public domain did not appear. However, similar concepts were developed by French jurists in the 18th century. Instead of "public domain", they used terms such as publici juris or propriété publique to describe works that were not covered by copyright law; the phrase "fall in the public domain" can be traced to mid-19th century France to describe the end of copyright term. The French poet Alfred de Vigny equated the expiration of copyright with a work falling "into the sink hole of public domain" and if the public domain receives any attention from intellectual property lawyers it is still treated as little more than that, left when intellectual property rights, such as copyright and trademarks, expire or are abandoned. In this historical context Paul Torremans describes copyright as a, "little coral reef of private right jutting up from the ocean of the public domain." Copyright law differs by country, the American legal scholar Pamela Samuelson has described the public domain as being "different sizes at different times in different countries".
Definitions of the boundaries of the public domain in relation to copyright, or intellectual property more regard the public domain as a negative space. According to James Boyle this definition underlines common usage of the term public domain and equates the public domain to public property and works in copyright to private property. However, the usage of the term public domain can be more granular, including for example uses of works in copyright permitted by copyright exceptions; such a definition regards work in copyright as private property subject to fair-use rights and limitation on ownership. A conceptual definition comes from Lange, who focused on what the public domain should be: "it should be a place of sanctuary for individual creative expression, a sanctuary conferring affirmative protection against the forces of private appropriation that threatened such expression". Patterson and Lindberg described the public domain not as a "territory", but rather as a concept: "here are certain materials – the air we breathe, rain, life, thoughts, ideas, numbers – not subject to private ownership.
The materials that compose our cultural heritage must be free for all living to use no less than matter necessary for biological survival." The term public domain may be interchangeably used with other imprecise or undefined terms such as the "public sphere" or "commons", including concepts such as the "commons of the mind", the "intellectual commons", the "information commons". A public-domain book is a book with no copyright, a book, created without a license, or a book where its copyrights expired or have been forfeited. In most countries the term of protection of copyright lasts until January first, 70 years after the death of the latest living author; the longest copyright term is in Mexico, which has life plus 100 years for all deaths since July 1928. A notable exception is the United States, where every book and tale published prior to 1924 is in the public domain.
