The publication titled The Colophon, subtitled "A Book Collectors' Quarterly" or "A quarterly for booklovers," was a limited edition quarterly periodical begun late in 1929 and continuing in various guises until 1950.
 It was the brainchild of Elmer Adler (1884–1962), founder of Pynson Printers of New York City.
 His idea was that various printers around the world would be willing to contribute their time and expertise to produce signatures (articles) using their own choice of papers, typography and illustration.
 These articles would then be bound together in boards by Pynson Printers and marketed to 2,000 subscribers.

The Oxford University Society of Bibliophiles is a book collecting and bibliophile club run by, and primarily for, students at Oxford University.
 It was founded in 1950 by a group of young bibliophiles headed by John Granger, Bent Juel-Jensen and R. John Rickett, and the first meeting was held in Hilary Term of 1951.
 For fifty years the Society held regular lectures, visits and other events during the University terms, and many of the leading bibliographers, librarians, book collectors, booksellers and other literary figures of the period spoke to the Society or hosted visits.
 Many of the Society's junior members went on to become prominent figures in the world of books, and some later served as senior members of the Society.
 One of the most influential members was John Sparrow, Warden of All Souls, who encouraged a love of books and manuscripts in a generation of students, and hosted a termly "Warden's Meeting" at which members were encouraged to bring items from their own libraries to pass round and say a few words about; the tradition of the "Warden's Meeting" continued after 1986, when the Warden himself was too ill to host the meetings and, indeed, after his death in 1992.
 Another of the Society's traditions was the quality of the termly programme cards, often produced by the leading printers and private presses of the age, including the Oxford and Cambridge University Presses, the Rampant Lions Press, the Samson Press, the Fantasy Press, the Kit-Cat Press, Big Wheel Press, the Perpetua Press, the Incline Press, the Whittington Press, the Libanus Press, the Rocket Press, the Stanbrook Abbey Press and the Stamperia Valdonega.

The Mainz Psalter was the second major book printed with movable type in the West; the first was the Gutenberg Bible.
 It is a psalter commissioned by the Mainz archbishop in 1457.
 The Psalter introduced several innovations: it was the first book to feature a printed date of publication, a printed colophon, two sizes of type, printed decorative initials, and the first to be printed in three colours.
 The colophon also contains the first example of a printer's mark.
 It was the first important publication issued by Johann Fust and Peter Schoeffer following their split from Johannes Gutenberg.
Bookbreaking is the longstanding practice of removing pages (especially those containing maps or illustrations) from books, especially from rare books.
 Bookbreaking is most often motivated by a market situation in which the maps or illustrations in a book will have more value sold separately than the value of the intact book.
 Often this happens because book collectors judge minor defects in an old book so harshly as to make them seemingly unsaleable.
 This widespread practice probably peaked in the 1970s or 1980s, because the price for old engravings and especially for old maps was outstripping that of rare books.
 However—in part because so many rare, illustrated books were "broken" in this manner—the price of the intact books has now risen the point where an old book is typically worth more intact.
 Book collectors have also become more sophisticated in understanding minor condition problems.
