The pieces without a work number (such as the study drawings and desk records) are listed at the front of the inventory. These documents have been assigned an application number, d0 through d4 and t1 through t4.The selected projects have been arranged according to their original work number. This numbering runs from 5, 10, 15, etc. through to number 700. The pieces are arranged by project, where for the purpose of application, a t number was assigned for the drawings (e.g., t260) and a d number for the written records and documentation (e.g., d260). The amount of covers and/or rolls are listed after the numbers. Only the photographs and negatives are numbered individually (ph1 to ph73 and n1 to n8).
