Amazon.com description: Product Description: THE task of mending demands so much of the time and energy of library workers and is a factor of such economic importance in every public library that it cannot be put aside as incidental. It is hoped that these suggestions may give definite aid in this homely task which is ever present in all libraries. No attempt has been made to give instruction in the advanced processes of mending, as this at once encroaches on the art of binding. The best mending can be done only where an acquaintance with the construction of the book has been acquired through a study of the various processes of binding. Librarians are urged to visit binderies to see the various processes; and to study the art of binding under personal instruction of experienced binders whenever this is feasible.
