Detta är ett exempel på ett "kedjat bibliotek". Dessa härrörde från medeltiden, vilket är tidsperioden Thronespel är inspirerad av eller mönstrad av. Syftet var att hålla böcker från att bli stulen och gjordes vanligtvis bara på mer värdefulla böcker.
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. However, it also led to crowding and awkwardness when readers had to stand side by side, each holding a book or clumping so they could share one. 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.
