Never use an old accession number for a new book, even though the original book has disappeared from the library.
Record should be made of all books, pamphlets, reports, bulletins, magazines, etc., received by the library as gifts; and every gift should be promptly and courteously acknowledged in writing, even if previously acknowledged in person.

Keep this record in a blank book, alphabetizing all gifts by the names of the givers, with dates of receipt.

Books given should appear on the accession register the same as books purchased..
