This diary serves as John Henry Bliler's account of the Civil War. It was kept in the Bliler family, in some form since the Civil War, up until it was acquired by the repository.

It looks that Bliler copied over his original diary several times himself, and this last copy occupies all but a few leaves of the five exercise tablets. As noted in the description of Series 1, these first five exercise books could not possibly have contained a copy made any earlier than 1890. The only exception seems to be a portion of the last tablet, which is filled by entries copied over in pencil in 1944 by one of Bliler's descendants, Ardath Bliler Kelly, reportedly since the family copy had become quite damaged by then.

Thus, according to p. 56 of the typewritten transcript of the diary entries in the five exercise books, "[John Henry] Bliler copied his account of the Civil War three times during his lifetime. The last copy was made shortly before his death in 1924." On page number 116 in pencil in the fifth exercise book, an entry from March 31, 1944, made in different handwriting reads "The following copied from by [sic.] originally by Ardath Bliler Kelly, granddaughter of the narrator [sic.]. The original is ragged and yellowed and crumbling." Entries which are thus copied on p. 116-123 of this last exercise book are out of order, dated June 24, [1865] - June 29, 1865, followed by a note in Ardath Bliler Kelly's hand, "A portion of the original omitted in the copy," then the dates January 24 - January 31, 1865.

The typed transcript and index were probably made by Roy K. Bliler later than 1944, and not too long previous to when it was received by the repository. This transcript preserves the original order of John Henry Bliler's diary entries.

A collection of letters to and from Robert E. Howard, from circa 1920-1936, with miscellaneous Howard items, copies of magazines featuring Howard stories, and books containing Howard stories and novels. Also included are a number of items relating to films based on Howard's works.

The Arkham House Collection consists of correspondence from August Derleth to Howard Wandrei. Derleth, a writer, founded Arkham House to publish and keep in print the work of Howard Phillips Lovecraft, a friend and fellow writer. Lovecraft died in 1937; for the next two years Derleth tried unsuccessfully to find a publisher for Lovecraft's writings. Using money from prepaid orders and the personal investment of Donald Wandrei (brother of Howard Wandrei), Derleth founded Arkham House in 1939. Arkham House published science fiction works by Lovecraft and other writers such as Algernon Blair, Clark Ashton Smith and Henry S. Whitehead.

In his letters to fellow science-fiction writer Howard Wandrei, August Derleth writes about his publishing efforts at Arkham House, his own writing career and the details of his personal life. His letters also mention other authors and publishing houses. The letters date from 1930-1953; most letters are accompanied by the original stamped envelopes.

The collection spans Bill Crider's entire career. A near-complete run of manuscripts traces his writing career, supplemented by a correspondence file, miscellaneous material, and books and magazines. A long run of "DAPA-EM," the organ of a mystery writer's amateur press association completes the collection.

This collection includes speeches, editorials, and articles written by Eugene Butler, dating from 1927 through 1987. These documents deal with a broad spectrum of issues of the day from Prohibition to bussing but focus primarily on agricultural topics.

Other items in the collection include extensive material on the Progressive Farmer Company, cotton, and the Progressive Farmer Master Farm Family Award and individual winners.
