27. All books, unless otherwise specified, will be fastened finally into the covers by pasting down end papers. Tight-back books will in addition have the back glued to the book.
28. Books should be loose-back unless otherwise specified.
29. Edges should be sprinkled unless the library specifies gilding on top. The color used may be varied to harmonize with the color of the book.
30. Books must be pressed until thoroughly dry.
31. Binders must keep a record of each book, whether periodical or not, which has a volume number.
This record, commonly known as a "rub" or "rub-off," shows the size of the book, kind of binding and exact lettering. Whenever other volumes of the same work or same periodical are received they will be bound according to this record, unless the librarian has specified a different material, or different lettering. In such a case the matter must be referred to the librarian before the book is bound. If a binder receives a book with a volume number and has no record of previous volumes, he should ask the librarian for a sample volume, unless it is obviously a book for which there could be no sample, such as the first volume of a periodical giving contemporary dates.
32. The binder is expected to paste in book-pockets and book-plates when furnished by the library but may charge extra for the work.
33. The best gold leaf must be used in lettering unless cover is light enough in color to take ink. Leather labels should never be used.
