Binding and mending
Binding a book means not only covering it, but preserving it. Good binding, even at a high price, educates the public taste and promotes a desire to protect the library from injury and loss. Cheap binding degrades books and costs more in the end than good work.
Keep in a bindery-book, which may be any simple blank book, or one especially made for the purpose (see Library Bureau catalog), a record of each volume that the library binds or rebinds.
