The "collected materials" include a wide range of items: correspondence, memoranda, directives, minutes, account books, press releases, publications, clippings, photographs, flags, banners, posters, blank forms, letterheads, envelopes, rubber stamps, etc. Many items were acquired in multiple copies, and substantial duplication still exists, both within the "collected materials" and between them and other files. The State Library collated groups of duplicate materials and offered them to other libraries (see RG 12, VII, 3)
