This collection is made up of eight series. Series I is comprised of correspondence, listed by name of correspondent, whether the letter is to or from Blunden. The letters are assumed to be from Blunden to the correspondent unless otherwise noted. There are several letters from and to third parties and this is noted in the entry. Series II is made up of essays written by Blunden. Series III is Miscellaneous, which contains such things as transcriptions of other writers' poetry by Blunden and a bibliography of Blunden's works. Series IV is an inventory of the pamphlets. These pamphlets are not shelved with the collection, but rather they are shelved with the Blunden books. Series V is made up of about forty photographs, mostly showing Blunden in intimate scenes, such as with his family at tea. Paul Engle and Somerset Maugham appear in photos with Blunden. Series VI is comprised of Blunden's poems, mostly handwritten in Blunden's meticulous script. Series VII is made up of reviews and Series VIII is speeches.

The University of Iowa Special Collections Department also houses a collection of Blunden's books.
