Contains minor spoilers for “Dragonstone,” the Season 7 premiere of Game of Thrones
In Sunday night’s season premiere, Game of Thrones continued its long streak of drawing on the real past to make Westeros come alive by using Samwell Tarly to make a point about real medieval libraries — sort of.
As Sam gets to know the ropes of the Citadel, part of his thankless job is to work at the library, which offers viewers a chance to get a good look at the grandest library in the Thrones universe.

Such chains were a common sight in early libraries, for a reason that Sam handily illustrates when he makes off with books that are clearly not intended for public circulation. In 1931, the Oxford scholar B.H. Streeter published a study of England’s early chained libraries, he explained where the tradition came from:

However, here those real chained libraries diverge from their fictional counterpart, as the whole point of the chains was that the books stayed attached to their shelves. As Streeter explained, the fact of the chain determined much of…
