In the “Remarks” column of the duplicate copy can be entered the date of receipt when a parcel of books is being marked off. Libraries which use vertical and similar filing systems preserve carbon copies of order lists and file them under appropriate headings, and dispense with the ruled order sheet given above, merely accompanying the lists with a general official order. Where a duplicated (cyclostyled, mimeographed, etc.) list of suggestions is used for the committee, a copy of this, with the committee’s adjustments, can be used as an order list. The bookseller’s invoice and the books are checked by the suggestion slips, and discrepancies of price or books not supplied are revealed immediately. The use of books for entering lists, or for other library record purposes, is gradually giving way to the more mobile and economical systems to be obtained by the use of expansible files and card indexes.
