It has been the purpose of the writer in these chapters on library bookbinding to set forth as clearly as possible the best information relating to processes, materials, routine and various other lesser matters pertaining to bookbinding which must be taken into consideration by librarians, or by assistants in charge of binding departments. Although much of this information exists elsewhere in printed form, it is scattered through various books and articles. In some respects, therefore, this book is a gathering together of scattered material. It is hoped, however, that there is enough new material to make the book of interest to those who deal daily with binding problems, and that the book as a whole may help to solve some of the questions relating to binding in libraries both large and small.
