Chained library

（重定向自Chained libraries）

A chained library is a library where the books are attached to their bookcase by a chain, which is sufficiently long to allow the books to be taken from their shelves and read, but not removed from the library itself. This would prevent theft of the library's materials. The practice was usual for reference libraries (that is, the vast majority of libraries) from the Middle Ages to approximately the 18th century. However, since the chaining process was also expensive, it was not used on all books. Only the more valuable books in a collection were chained. This included reference books and large books.
