Lindahl's personal journals form the bulk of the collection. The journals are composed of traditional entries, interspersed with drafts of poetry and correspondence. Other materials include plays, poetry, prose, and reviews of the writings of others, in various stages of development. The materials are arranged by genre: journals, performance pieces, plays, poetry anthologies and poetry drafts, prose, and reviews. The journals are arranged chronologically by the first dated entry; however, they do not run consecutively, and there is some overlap between various volumes. The other materials within each genre category are arranged alphabetically by final title, when known. Stage directions, works, flyers, and reviews document his performance pieces. Lindahl re-worked pieces over time, and early drafts of some his pieces can be found in the "Homework" folders, which also contain Lindahl's schoolwork, primarily from his high school and college writing classes. The arrangement of the untitled works reflects the order in which they were found.
