The collection is arranged by item type. Information on Sigma Xi is minimal, consisting of some proposals and planning notes. The information put out by SDSU for the Science Fair is quite comprehensive, including programs and brochures from a number of years, as are the budgets and expense records. There is a good amount of material relating to Science Fair winners and their projects, though the dates of this information are quite random. The publications for ISEF are also quite comprehensive, including rule books, participant forms, programs, touring and housing information, and books of abstracts of participant research.
