The Alternative Service Book 1980 (ASB) was the first complete prayer book produced by the Church of England since 1662. Its name derives from the fact that it was proposed not as a replacement for the 1662 Book of Common Prayer (BCP) but merely as an alternative to it. In practice, it was so popular that the various printers had to produce several editions very quickly and churches which retained the BCP drew attention to this fact as something to be noted. The Prayer Book Society soon complained that it was becoming hard to find a church which used the old prayer book and that theological colleges were not introducing students to it. It has now been replaced by Common Worship.

The 1662 Book of Common Prayer is an authorised liturgical book of the Church of England and other Anglican bodies around the world. In continuous print and regular use for over 360 years, the 1662 prayer book is the basis for numerous other editions of the Book of Common Prayer and other liturgical texts. Noted for both its devotional and literary quality, the 1662 prayer book has influenced the English language, with its use alongside the King James Version of the Bible contributing to an increase in literacy from the 16th to the 20th century.
