Items housed in the collection's boxes (1-15) are primarily correspondence between Elliot and others (Boxes 2 & 3), or ephemera that includes, but is not limited to, dust jackets and items found by the original archivist while processing the collection. Also included are small-format items, periodicals, newsletters, etc.

Book jackets have been removed and can be found in the Archives and other ephemera, such as correspondence or clippings found in the books, are housed separately in acid free folders, but cross-referenced to the item where found. Many of the items in the Michigan Authors Collection duplicate those found elsewhere in the book and archival collection, but come together here as Elliott's particular collection. Arrangement is alphabetical by author.
