Bohemia is the westernmost and largest historical region of the Czech lands in the present-day Czech Republic. In a broader meaning, Bohemia sometimes refers to the entire Czech territory, including Moravia and Czech Silesia in a historical context, such as the Lands of the Bohemian Crown ruled by Bohemian kings. Bohemia was a duchy of Great Moravia an independent principality, a kingdom in the Holy Roman Empire, subsequently a part of the Habsburg Monarchy and the Austrian Empire. After World War I and the establishment of an independent Czechoslovak state, Bohemia became a part of Czechoslovakia. Between 1938 and 1945, border regions with sizeable German-speaking minorities of all three Czech lands were joined to Nazi Germany as the Sudetenland; the remainder of Czech territory became the Second Czechoslovak Republic and was subsequently occupied as the Protectorate of Bohemia and Moravia, In 1969, the Czech lands were given autonomy within Czechoslovakia as the Czech Socialist Republic. In 1990, the name was changed to the Czech Republic, which became a separate state in 1993 with the split of Czechoslovakia.
Until 1948, Bohemia was an administrative unit of Czechoslovakia as one of its "lands". Since administrative reforms have replaced self-governing lands with a modified system of "regions" which do not follow the borders of the historical Czech lands. However, the three lands are mentioned in the preamble of the Constitution of the Czech Republic: "We, citizens of the Czech Republic in Bohemia and Silesia…"Bohemia had an area of 52,065 km2 and today is home to 6.5 million of the Czech Republic's 10.5 million inhabitants. Bohemia was bordered in the south by Upper and Lower Austria, in the west by Bavaria and in the north by Saxony and Lusatia, in the northeast by Silesia, in the east by Moravia. Bohemia's borders were marked by mountain ranges such as the Bohemian Forest, the Ore Mountains, the Krkonoše, a part of the Sudetes range. In the 2nd century BC, the Romans were competing for dominance in northern Italy with various peoples including the Gauls-Celtic tribe Boii; the Romans defeated the Boii at the Battle of Mutina.
After this, many of the Boii retreated north across the Alps. Much Roman authors refer to the area they had once occupied as Boiohaemum; the earliest mention was by Tacitus' Germania 28, mentions of the same name are in Strabo and Velleius Paterculus. The name appears to include the tribal name Boi- plus the Germanic element *haimaz "home"; this Boiohaemum was isolated to the area where King Marobod's kingdom was centred, within the Hercynian forest. Emperor Constantine VII in 10th century De Administrando Imperio mentioned the region as Boïki; the Czech name "Čechy" is derived from the name of the Slavic ethnic group, the Czechs, who settled in the area during the 6th or 7th century AD. Bohemia, like neighbouring Bavaria, is named after the Boii, who were a large Celtic nation known to the Romans for their migrations and settlement in northern Italy and other places. Another part of the nation moved west with the Helvetii into southern France, one of the events leading to the interventions of Julius Caesar's Gaulish campaign of 58 BC.
The emigration of the Helvetii and Boii left southern Germany and Bohemia a inhabited "desert" into which Suebic peoples arrived, speaking Germanic languages, became dominant over remaining Celtic groups. To the south, over the Danube, the Romans extended their empire, to the southeast in present-day Hungary, were Dacian peoples. In the area of modern Bohemia the Marcomanni and other Suebic groups were led by their king Marobodus, after suffering defeat to Roman forces in Germany, he took advantage of the natural defenses provided by its forests. They were able to maintain a strong alliance with neighbouring tribes including the Lugii, Hermunduri and Buri, sometimes controlled by the Roman Empire, sometimes in conflict with it, for example in the second century when they fought Marcus Aurelius. In late classical times and the early Middle Ages, two new Suebic groupings appeared to the west of Bohemia in southern Germany, the Alemanni, the Bavarians. Many Suebic tribes from the Bohemian region took part in such movements westwards settling as far away as Spain and Portugal.
With them were tribes who had pushed from the east, such as the Vandals, Alans. Other groups pushed southwards towards Pannonia; the last known mention of the kingdom of the Marcomanni, concerning a queen named Fritigil is in the 4th century, she was thought to have lived in or near Pannonia. The Suebian Langobardi, who moved over many generations from the Baltic Sea, via the Elbe and Pannonia to Italy, recorded in a tribal history a time spent in "Bainaib". After this migration period, Bohemia was repopulated around the 6th century, Slavic tribes arrived from the east, their language began to replace the older Germanic and Sarmatian ones; these are precursors of today's Czechs, though the exact amount of Slavic immigration is a subject of debate. The Slavic influx was divided into three waves; the first wave came from the
OCLC Online Computer Library Center, Incorporated d/b/a OCLC is an American nonprofit cooperative organization "dedicated to the public purposes of furthering access to the world's information and reducing information costs". It was founded in 1967 as the Ohio College Library Center. OCLC and its member libraries cooperatively produce and maintain WorldCat, the largest online public access catalog in the world. OCLC is funded by the fees that libraries have to pay for its services. OCLC maintains the Dewey Decimal Classification system. OCLC began in 1967, as the Ohio College Library Center, through a collaboration of university presidents, vice presidents, library directors who wanted to create a cooperative computerized network for libraries in the state of Ohio; the group first met on July 5, 1967 on the campus of the Ohio State University to sign the articles of incorporation for the nonprofit organization, hired Frederick G. Kilgour, a former Yale University medical school librarian, to design the shared cataloging system.
Kilgour wished to merge the latest information storage and retrieval system of the time, the computer, with the oldest, the library. The plan was to merge the catalogs of Ohio libraries electronically through a computer network and database to streamline operations, control costs, increase efficiency in library management, bringing libraries together to cooperatively keep track of the world's information in order to best serve researchers and scholars; the first library to do online cataloging through OCLC was the Alden Library at Ohio University on August 26, 1971. This was the first online cataloging by any library worldwide. Membership in OCLC is based on use of services and contribution of data. Between 1967 and 1977, OCLC membership was limited to institutions in Ohio, but in 1978, a new governance structure was established that allowed institutions from other states to join. In 2002, the governance structure was again modified to accommodate participation from outside the United States.
As OCLC expanded services in the United States outside Ohio, it relied on establishing strategic partnerships with "networks", organizations that provided training and marketing services. By 2008, there were 15 independent United States regional service providers. OCLC networks played a key role in OCLC governance, with networks electing delegates to serve on the OCLC Members Council. During 2008, OCLC commissioned two studies to look at distribution channels. In early 2009, OCLC negotiated new contracts with the former networks and opened a centralized support center. OCLC provides bibliographic and full-text information to anyone. OCLC and its member libraries cooperatively produce and maintain WorldCat—the OCLC Online Union Catalog, the largest online public access catalog in the world. WorldCat has holding records from private libraries worldwide; the Open WorldCat program, launched in late 2003, exposed a subset of WorldCat records to Web users via popular Internet search and bookselling sites.
In October 2005, the OCLC technical staff began a wiki project, WikiD, allowing readers to add commentary and structured-field information associated with any WorldCat record. WikiD was phased out; the Online Computer Library Center acquired the trademark and copyrights associated with the Dewey Decimal Classification System when it bought Forest Press in 1988. A browser for books with their Dewey Decimal Classifications was available until July 2013; until August 2009, when it was sold to Backstage Library Works, OCLC owned a preservation microfilm and digitization operation called the OCLC Preservation Service Center, with its principal office in Bethlehem, Pennsylvania. The reference management service QuestionPoint provides libraries with tools to communicate with users; this around-the-clock reference service is provided by a cooperative of participating global libraries. Starting in 1971, OCLC produced catalog cards for members alongside its shared online catalog. OCLC commercially sells software, such as CONTENTdm for managing digital collections.
It offers the bibliographic discovery system WorldCat Discovery, which allows for library patrons to use a single search interface to access an institution's catalog, database subscriptions and more. OCLC has been conducting research for the library community for more than 30 years. In accordance with its mission, OCLC makes its research outcomes known through various publications; these publications, including journal articles, reports and presentations, are available through the organization's website. OCLC Publications – Research articles from various journals including Code4Lib Journal, OCLC Research, Reference & User Services Quarterly, College & Research Libraries News, Art Libraries Journal, National Education Association Newsletter; the most recent publications are displayed first, all archived resources, starting in 1970, are available. Membership Reports – A number of significant reports on topics ranging from virtual reference in libraries to perceptions about library funding. Newsletters – Current and archived newsletters for the library and archive community.
Presentations – Presentations from both guest speakers and OCLC research from conferences and other events. The presentations are organized into five categories: Conference presentations, Dewey presentations, Distinguished Seminar Series, Guest presentations, Research staff
Petrus Bertius was a Flemish philosopher, historian and cartographer. Bertius published much in mathematics, historical and theological works, but he is now best known as cartographer with his edition of the Geographia of Ptolemy, for its atlas, he was born in Beveren, the son of a Flemish preacher Pieter Michielszoon Bardt, who left Flanders for religious exile in London around 1568, with his family. In 1577 Petrus Bertius returned to the Netherlands, he continued travelling in Europe. In 1593 he was appointed to subregent of the Leiden Statencollege, marrying in the same year Maritgen, daughter of Johannes Kuchlinus, the first regent of the Statencollege, whom he would succeeded after his death in 1606 as a regent, he was connected by marriage to Jodocus Hondius and Pieter van den Keere, his brothers-in-law and both cartographers, this would influence his life. Bertius wrote an introduction to Boethius's Consolations of Philosophy, published in Giovanni Antonio Volpi's edition of the text in 1721.
Bertius was a friend of Jacobus Arminius, spoke at his funeral in 1609. A controversy arose with Francis Gomarus, the chief opponent of Arminianism, on the basis of the published version of the funeral oration. In 1612 Bertius published Hymenaeus desertor, a Latin work that went further than Arminius in theology, against the advice of fellow Remonstrants; the Hymenaeus desertor was circulated, but was unpopular: William Louis, Count of Nassau-Dillenburg disliked it, Johan van Oldenbarnevelt with other politicians felt that Bertius had gone against them. Bertius persisted, however, in 1613 with a Dutch translation. Bertius lost his teaching position, was forbidden to give private lessons. In 1618 Bertius was given an appointment as a cosmographer to the court of Louis XIII, his career in cartography had started in 1598, with the publication of a Latin edition of a miniature atlas Caert Thresoor by Barent Langenes, which he translated as Tabulae contractae. His Theatrum geographiae veteris had commended him to King Louis.
When his academic prospects in the Netherlands were cut down, he went to France. He became in 1620 a convert to the Roman Catholic Church, whereupon professor of rhetoric at the Collège de Boncourt, a part of the University of Paris. In 1622 Louis XIII set up a new personal chair in mathematical sciences in the royal college for Bertius, granted him the title of royal historian, he died in Paris. 1609: Liick-oratie over de doot van den Eerweerdighen ende wytberoemden Heere Jacobus Arminius 1612: Hymenaeus desertor: sive de sanctorum apostasia problemata duo. 1616: Commentariorum Rerum Germanicarum libri tres, including commentary on the Tabula Peutingeriana 1619: Theatri Geographiae Veteris 1625: Notitia Chorographica Episcopatuum Galliae Bertius Inlet in Antarctica is named after Petrus Bertius.

Corsica is an island in the Mediterranean Sea and one of the 18 regions of France. It is located southeast of the French mainland and west of the Italian Peninsula, with the nearest land mass being the Italian island of Sardinia to the immediate south. A single chain of mountains makes up two-thirds of the island. While being part of Metropolitan France, Corsica is designated as a territorial collectivity by law; as a territorial collectivity, Corsica enjoys a greater degree of autonomy than other French regions. The island formed a single department until it was split in 1975 into two historical departments: Haute-Corse and Corse-du-Sud, with its regional capital in Ajaccio, the prefecture city of Corse-du-Sud. Bastia, the prefecture city of Haute-Corse, is the second largest settlement in Corsica; the two departments, the region of Corsica, merged again into a single territorial collectivity in 2018. After being ruled by the Republic of Genoa since 1284, Corsica was an Italian-speaking independent republic from 1755, until it was ceded by the Republic of Genoa to Louis XV as part of a pledge for debts and conquered in 1769.
Napoleon Bonaparte was born the same year in Ajaccio, his ancestral home, Maison Bonaparte, is today a significant visitor attraction and museum. Due to Corsica's historical ties with the Italian peninsula, the island retains to this day many Italian cultural elements: the native tongue is recognized as a regional language by the French government; the origin of the name Corsica remains a mystery. To the Ancient Greeks it was known as Kalliste, Cyrnos, Cernealis, or Cirné. Of these Cyrnos, Cernealis, or Cirné derive from the most ancient Greek name of the island, "Σειρηνούσσαι", the same Sirens mentioned in Homer's Odyssey. Corsica has been occupied continuously since the Mesolithic era, it acquired an indigenous population, influential in the Mediterranean during its long prehistory. After a brief occupation by the Carthaginians, colonization by the ancient Greeks, an only longer occupation by the Etruscans, it was incorporated by the Roman Republic at the end of the First Punic War and, with Sardinia, in 238 BC became a province of the Roman Republic.
The Romans, who built a colony in Aléria, considered Corsica as one of the most backward regions of the Roman world. The island produced sheep, honey and wax, exported many slaves, not well considered because of their fierce and rebellious character. Moreover, it was known for its cheap wines, exported to Rome, was used as a place of relegation, one of the most famous exiles being the Roman philosopher Seneca. Administratively, the island was divided in pagi, which in the Middle Ages became the pievi, the basic administrative units of the island until 1768. During the diffusion of Christianity, which arrived quite early from Rome and the Tuscan harbors, Corsica was home to many martyrs and saints: among them, the most important are Saint Devota and Saint Julia, both patrons of the island. Corsica was integrated into Roman Italy by Emperor Diocletian. In the 5th century, the western half of the Roman Empire collapsed, the island was invaded by the Vandals and the Ostrogoths. Recovered by the Byzantines, it soon became part of the Kingdom of the Lombards.
This made it a dependency of the March of Tuscany. Pepin the Short, king of the Franks and Charlemagne's father, expelled the Lombards and nominally granted Corsica to Pope Stephen II. In the first quarter of the 11th century and Genoa together freed the island from the threat of Arab invasion. After that, the island came under the influence of the republic of Pisa. To this period belong the many polychrome churches which adorn the island, Corsica experienced a massive immigration from Tuscany, which gave to the island its present toponymy and rendered the language spoken in the northern two-thirds of the island close to the Tuscan dialect. Due to that began the traditional division of Corsica in two parts, along the main chain of mountains going from Calvi to Porto-Vecchio: the eastern Banda di dentro, or Cismonte, more populated and open to the commerce with Italy, the western Banda di fuori, or Pomonte deserted and remote; the crushing defeat experienced by Pisa in 1284 in the Battle of Meloria against Genoa had among its consequences the end of the Pisan rule and the beginning of the Genoese influence in Corsica: this was contested by the King of Aragon, who in 1296 had received from the Pope the investiture over Sardinia and Corsica.
A popular revolution against this and the feudal lords, led by Sambucuccio d'Alando, got the aid of Genoa. After that, the Cismonte was ruled after the Italian experience; the following 150 years were a period of conflict, when the Genoese rule was contested by Aragon, the local lords, the comuni and the Pope: in 1450 Genoa ceded the administration of the island to its main bank, the Bank of Saint George, which brought peace. In the 16th century, the island entered into the fight between Spain and France for the supremacy in Italy. In 1553, a Franco-Ottoman fleet occupied Corsica, but the reaction of Spain and Genoa, led by Andrea Doria, reestablished the Genoese supremacy on the island, confirmed by the Peace of Cateau-Cambresis; the unlucky protagonist of this episode was Sampiero di Bastelica, who would come to be considered a hero of t
Gerardus Mercator was a 16th-century Southern Dutch cartographer and cosmographer. He was renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing as straight lines—an innovation, still employed in nautical charts. Mercator was one of the founders of the Netherlandish school of cartography and is considered the most notable figure of the school in its golden age. In his own day, he was a notable geographer, maker of globes and scientific instruments. In addition, he had interests in theology, history and geomagnetism, he was an accomplished engraver, calligrapher. Unlike other great scholars of the age he travelled little and his knowledge of geography came from his library of over one thousand books and maps, from his visitors and from his vast correspondence with other scholars, travelers and seamen. Mercator's early maps were in large formats suitable for wall mounting but in the second half of his life, he produced over 100 new regional maps in a smaller format suitable for binding into his Atlas of 1595.
This was the first appearance of the word Atlas in a geographical context but Mercator used it as a neologism for a treatise on the creation and description of the universe, not a collection of maps. He chose the word as a commemoration of the Titan Atlas, "King of Mauretania", whom he considered to be the first great geographer. A large part of Mercator's income came from sales of his celestial globes. For sixty years they were considered the finest in the world, were sold in such great numbers that there are many surviving examples; this was a substantial enterprise involving the manufacture of the spheres, printing the gores, building substantial stands and distributing all over Europe. He was renowned for his scientific instruments his astrolabes and astronomical rings used to study the geometry of astronomy and astrology. Mercator wrote on geography, philosophy and theology. All of the wall maps were engraved with copious text on the region concerned; as an example the famous world map of 1569 is inscribed with over 5000 words in fifteen legends.
The 1595 Atlas has about 120 pages of maps and illustrated title pages but a greater number of pages are devoted to his account of the creation of the universe and descriptions of all the countries portrayed. His table of chronology ran to some 400 pages fixing the dates of earthly dynasties, major political and military events, volcanic eruptions and eclipses, he wrote on the gospels and the old testament. Mercator was a devout Christian born into a Catholic family at a time when Martin Luther's Protestantism was gaining ground, he never declared himself as a Lutheran but he was sympathetic and he was accused of heresy. This period of persecution is the major factor in his move from Catholic Leuven to a more tolerant Duisburg where he lived for the last thirty years of his life. Walter Ghim, Mercator's friend and first biographer, describes him as sober in his behaviour, yet cheerful and witty in company, never more happy than in debate with other scholars. Above all he was studious until his dying days.
Gerardus Mercator was born Geert or Gerard Kremer, the seventh child of Hubert Kremer and his wife Emerance in Rupelmonde, a small village to the immediate southwest of Antwerp in the Burgundian Netherlands. His parents resided in Gangelt in the Duchy of Jülich and at the time of the birth, they were visiting Hubert's brother Gisbert de Kremer. Hubert was a poor artisan, a shoemaker by trade, but Gisbert, a priest, was a man of some importance in the community, their stay in Rupelmonde was brief and within six months they returned to Gangelt and there Mercator spent his earliest childhood until the age of six. In 1518, the Kremer family moved back to Rupelmonde motivated by the deteriorating conditions in Gangelt—famine and lawlessness. Mercator would have attended the local school in Rupelmonde from the age of seven, when he arrived from Gangelt, there he would have been taught the basics of reading, writing and Latin. After Hubert's death in 1526, Gisbert became Mercator's guardian. Hoping that Mercator might follow him into the priesthood, he sent the 15-year-old Geert to the famous school of the Brethren of the Common Life at's-Hertogenbosch in the Duchy of Brabant.
The Brotherhood and the school had been founded by the charismatic Geert Groote who placed great emphasis on study of the Bible and, at the same time, expressed disapproval of the dogmas of the church, both facets of the new "heresies" of Martin Luther propounded only a few years earlier in 1517. Mercator would follow similar precepts in life – with problematic outcomes. During his time at the school the headmaster was Georgius Macropedius, under his guidance Geert would study the Bible, the trivium and classics such as the philosophy of Aristotle, the natural history of Pliny and the geography of Ptolemy. All teaching at the school was in Latin and he would read and converse in Latin – and give himself a new Latin name, Gerardus Mercator Rupelmundanus, Mercator being the Latin translation of Kremer, which means "merchant"; the Brethren were renowned for their scriptorium and here Mercator might have encountered the italic script which he employed in his work. The brethren were renowned for their thoroughness
Sicily is the largest island in the Mediterranean Sea and one of the 20 regions of Italy. It is one of the five Italian autonomous regions, in Southern Italy along with surrounding minor islands referred to as Regione Siciliana. Sicily is located in the central Mediterranean Sea, south of the Italian Peninsula, from which it is separated by the narrow Strait of Messina, its most prominent landmark is Mount Etna, the tallest active volcano in Europe, one of the most active in the world 3,329 m high. The island has a typical Mediterranean climate; the earliest archaeological evidence of human activity on the island dates from as early as 12,000 BC. By around 750 BC, Sicily had three Phoenician and a dozen Greek colonies and, for the next 600 years, it was the site of the Sicilian Wars and the Punic Wars. After the fall of the Roman Empire in the 5th century AD, Sicily was ruled during the Early Middle Ages by the Vandals, the Ostrogoths, the Byzantine Empire, the Emirate of Sicily; the Norman conquest of southern Italy led to the creation of the Kingdom of Sicily, subsequently ruled by the Hohenstaufen, the Capetian House of Anjou and the House of Habsburg.
It was unified under the House of Bourbon with the Kingdom of Naples as the Kingdom of the Two Sicilies. It became part of Italy in 1860 following the Expedition of the Thousand, a revolt led by Giuseppe Garibaldi during the Italian unification, a plebiscite. Sicily was given special status as an autonomous region on 15th May 1946, 18 days before the Italian constitutional referendum of 1946. Albeit, much of the autonomy still remains unapplied financial autonomy, because the autonomy-activating laws have been deferred to be approved by the parithetic committee, since 1946. Sicily has a rich and unique culture with regard to the arts, literature and architecture, it is home to important archaeological and ancient sites, such as the Necropolis of Pantalica, the Valley of the Temples and Selinunte. Sicily has a triangular shape, earning it the name Trinacria. To the east, it is separated from the Italian mainland by the Strait of Messina, about 3 km wide in the north, about 16 km wide in the southern part.
The northern and southern coasts are each about 280 km long measured as a straight line, while the eastern coast measures around 180 km. The total area of the island is 25,711 km2, while the Autonomous Region of Sicily has an area of 27,708 km2; the terrain of inland Sicily is hilly and is intensively cultivated wherever possible. Along the northern coast, the mountain ranges of Madonie, 2,000 m, Nebrodi, 1,800 m, Peloritani, 1,300 m, are an extension of the mainland Apennines; the cone of Mount Etna dominates the eastern coast. In the southeast lie the lower Hyblaean Mountains, 1,000 m; the mines of the Enna and Caltanissetta districts were part of a leading sulphur-producing area throughout the 19th century, but have declined since the 1950s. Sicily and its surrounding small islands have some active volcanoes. Mount Etna is the largest active volcano in Europe and still casts black ash over the island with its ever-present eruptions, it stands 3,329 metres high, though this varies with summit eruptions.
It is the highest mountain in Italy south of the Alps. Etna covers an area of 1,190 km2 with a basal circumference of 140 km; this makes it by far the largest of the three active volcanoes in Italy, being about two and a half times the height of the next largest, Mount Vesuvius. In Greek mythology, the deadly monster Typhon was trapped under the mountain by Zeus, the god of the sky. Mount Etna is regarded as a cultural symbol and icon of Sicily; the Aeolian Islands in the Tyrrhenian Sea, to the northeast of mainland Sicily form a volcanic complex, include Stromboli. The three volcanoes of Vulcano and Lipari are currently active, although the latter is dormant. Off the southern coast of Sicily, the underwater volcano of Ferdinandea, part of the larger Empedocles volcano, last erupted in 1831, it is located between the island of Pantelleria. The autonomous region includes several neighbouring islands: the Aegadian Islands, the Aeolian Islands and Lampedusa; the island is drained by several rivers, most of which flow through the central area and enter the sea at the south of the island.
The Salso flows through parts of Enna and Caltanissetta before entering the Mediterranean Sea at the port of Licata. To the east, the Alcantara flows through the province of Messina and enters the sea at Giardini Naxos, the Simeto, which flows into the Ionian Sea south of Catania. Other important rivers on the island are the Platani in the southwest. Sicily has a typical Mediterranean climate with mild and wet winters and hot, dry summers with changeable intermediate seasons. On the coasts the south-western, the climate is affected by the African currents and summers can be scorching. Sicily is seen as an island of warm winters but above all along the Tyrrhenian coast and in the inland areas, winters can be cold, with typical continental climate. Snow falls in abundance above 900–1000 metres, but stronger cold waves can carry it in the hills and in coastal cities on the northern coast of the island; the interi
