California Code, Government Code - GOV § 29747

The auditor shall prepare duplicate lists of all claims he allows, showing as to each claim: date allowed, warrant number, name of claimant, and amount allowed. He shall certify that the lists are correct, file one copy in the office of the board and preserve the other or a photographic copy thereof in his own office. As to such claims the lists constitute, respectively, the allowance book and the warrant book. If the allowance book is dispensed with by the board of supervisors pursuant to Section 25102, the auditor shall prepare only a single list of all claims he allows, in the form and according to the procedure required for duplicate lists, and shall file the list in his office as the warrant book.
