=342. Records and Checks.=--When a lot of books for binding is sent out it must be accompanied by a set of instructions to the binder, and a copy of this must be retained at the library as a record and to check the books when returned. The most usual plan is to send out a binding sheet, ruled as in Fig. 129, on which are entered the particulars of the books requiring binding. These particulars are also entered in a binding book, ruled exactly the same as the sheets, and in the last column of this the books are marked off as returned. This result, and an actual facsimile copy, may be obtained by using a duplicating book, the sheet sent to the binder being so perforated as to be easily removable. The double copying involved in making out two separate sheets is thus avoided. It is usual to make the binder’s messenger check over and sign for every lot of books at the end of the page. Another method, which possesses the advantage of enabling the binder to distribute the work in his workshop, and makes every book carry its own instruction, is as follows: Procure a large book of perforated slips, with a counterpart page, unperforated, behind every page of slips, in the style of a manifold order book. Have these pages ruled as in Fig. 130, and progressively numbered. Or separate order slips, as under (Fig. 131), can be used, and their purport briefly entered in a binding book ruled to show title, class and date returned, with a column for a consecutive number, which of course would be written on the corresponding slip. +-------------------+-------------------+ | No. | Date sent | +===================+===================+ | LETTERING | +---------------------------------------+ | TITLE | | | +---------------------------------------+ | AUTHOR | | | +---------------------------------------+ | VOL.
