Stanley S. Slotkin was a successful Los Angeles businessman who owned the medical and party supply rental company Abbey Rents. He was also an avid collector of antique bibles and other rare books, amassing hundreds of thousands of books which he also regularly donated to various museums, universities and libraries across the United States. In the 1960s, Slotkin began to donate individual leaves from books to institutions rather than whole works, as he felt intact books were too often locked away where they could not be seen. The collection consists of 22 of these individual leaves donated by Slotkin, which he removed from various religious texts. Each leaf is mounted onto a sheet of paper which also includes a facsimile of the cover page of the work the leaf was originally from.
