Chained library

Okay kiddo, imagine you have a bunch of books in your bookshelf, but some of them are so long that they can't fit in just one shelf. So what do you do? You create a new, smaller shelf and put the rest of the book there, and then link them together. This is basically what a chained library is.

In a chained library, books that are too long to fit in one shelf are stored on multiple shelves, and each shelf is connected to the next one by a chain. This way, the books are all in order, and you can easily find the one you want by following the chain.

Chained libraries were common in Europe during the Middle Ages, when books were very valuable and had to be carefully protected. By chaining the books to the shelves, the librarians could prevent them from being stolen or damaged. And because the books were all in one place, people could come and study them without having to travel long distances to different libraries.

So there you have it, a chained library is just like your bookshelf, but instead of using multiple shelves, they used chains to link them all together.
