When we visit schools to install libraries, we always aim to leave the library as inviting and as practically useful as possible. Part of this process involves letter-labelling and jacketing your fiction, and Dewey-classifying and labelling your information books. Here's a bit of info about the process, where we source the stationery, and how you can continue to label, jacket and classify new stock into the future.
The jackets that we use for fiction stock come from Book Protectors. They are known as Lyfjackets, and the size to go for is 198mm, which is the standard size for fiction. We don't jacket books that are bigger or smaller than this - but if you'd like to, there are a bewildering amount of other sizes available. Jackets come in boxes of 100.
