The register records file numbers and titles for CUC files (ANUA 42), most of which were subsequently top-numbered or destroyed. There are two versions of the register: 1. Black springback binder: this is a working copy, heavily annotated with many handwritten entries, 2. Cardboard folder: this is a clean copy with all the file titles typed and has a cover sheet: 'Australian National University: School of General Studies: File Index'. Both versions are divided into primary headings from 1. Accounts to 17. Miscellaneous. The primary heading number (eg 2. Buildings and equipment) appears not to have been used as part of the file number, instead the secondary numbers (which appear randomly allocated) and a running number are used to identify files. For example, the first file listed under Buildings and equipment is 9/1. The file register allocates numbers from 8/1 through to 124/2 though not in order which may indicate that there was an earlier file register where the secondary numbers were allocated as required and this register was created to bring similar file titles together. Many file titles are crossed out and a new file number allocated, while others are stamped 'inactive', noted as 'destroyed' or 'PA' (put away). There is a note in the front of volume 1 referring to file 14.1.0.17 (ANUA 53) for the disposal and retention of files.
