The papers of Earl J. Larrison were in no discernible order when received. Therefore a series order was imposed during processing.

The first series reflects Larrison's zoological interests and includes typescripts of several of his books which had earlier been donated to Special Collections plus typescripts of other books articles, notes from several field trips, and correspondence, much of it with Harry W. Higman with whom he wrote a book on the animals of Mount Pilchuck in the Washington Cascades.

The second series concerns Larrison's interest in the writer Sir Walter Scott and contains copies of student papers on Scott from a variety of colleges and universities, and articles about his collection of Scott's books. There are also programs and cassette tapes of a Scott Colloquium held at the University of Florida in 1979, and a chronological bibliography of Scott's works.

The third series comprises personal and family papers. Included are Larrison's baby book, his diplomas and certificates, clippings about him, his appointment books, and items relating to his parents and other relatives.

The final series contains a large collection of photographs, slides and movie film. There are many unidentified photographs which belonged to Larrison's mother Marie Kuble. Some are of her friends, others of the Kuble and Miller families. Later pictures in this group show Earl as a small child. Some of these are taken by professional photographers, others are snapshots. These have not been arranged in any way. Some of the snapshots Larrison had copied so they exist in three forms, original photograph, copy negative, and copy print, each type is located in a separate folder. There are also some old picture postcards, probably purchased on a family vacation along the Columbia River Highway in Oregon. The remaining photographs were taken by Larrison in connection with his research. Some envelopes containing prints and negatives were numbered; the prints were placed in archival envelopes and identified by the roll number, the negatives were placed in archival negative storage pages and also identified by roll number. There is a photo log in the collection but it does not cover the majority of these numbered rolls. The remaining prints were identified by broad subject, e.g. habitats/life zones, birds, mammals. Prints and negatives which were together were kept together in folders, other negatives were placed at the end of the subject file, no attempt being made to match them with prints.

The slides which were originally in metal slide storage cases were placed in archival slide storage pages. Larrison's identifications were retained throughout. Included are pictures of Larrison's trip to Nairobi, Kenya, visits to various museums, many scenes of Idaho, and illustrative plates from books. Some of the slides are commercially produced.

Where more than two typescripts, including galley proofs, for a single book existed only the earliest and latest were retained. Duplicate photographs, when easily identified, were discarded. This, coupled with the removing of slides from their original storage cases, reduced the bulk of this collection by 1.5 cubic feet.
