This collection consists auction catalogs, largely for antiquarian books and manuscripts, dating from 1922 to 2024, from a wide variety of American, British, French, Germany, and other European auction houses. The large majority of these catalogs were collected over time by the William Andrews Clark Memorial Library, UCLA, but others were acquired as a part of various donations from the Heritage Bookshop, Howard Rootenberg, and the estate of William Dailey.
