This collection contains two series, Subject files and Writings. Arranged alphabetically, the first series, Subject files, contains Miss Evans's personal artifacts. Notable items within this series include an unsigned letter written circa 1835 to a Dr. Richard Harlan, a noted Philadelphia physician and naturalist, the program from her sister Caroline Veatch's funeral, and various architectural and botanical sketches.

The second series, Writings, is further organized into six sub-series including Journals; Plays; Verse; Short Stories; Essays; and Collected writings. The series and subsequent sub-series are arranged alphabetically, with the exception of journals, which have been given the primary position in the Writings series, and the Collected writings sub-series, which appears last and contains works Ms. Evans collected from various sources and either clipped or transcribed for her personal files.

The Journals sub-series contains volumes of works produced by Della Evans at various phases in her life. They contain a variety of materials, including biographical information, verse, newspaper clippings, collected works of other authors, and travel narratives.

The second sub-series in the Writings series contains Ms. Evans's essays. The essays in this collection are generally defined as works appearing to be non-fictional in subject matter, and have been arranged alphabetically by their titles. If a title was not assigned by the author, they have been alphabetized according to their subject matter.

Ms. Evans wrote a variety of plays, and these make up the third sub-series. The collection includes copies of her published plays, as well as pageants performed in local productions. These, like the above sub-series, have been arranged alphabetically by title.

The fourth sub-series contains short stories written by Ms. Evans. These are arranged by title and are essentially Ms. Evans's only substantial fictional works in prose form.

The fifth sub-series, Verse, contains Della Evans's various works of poetry. Within this sub-series one can track Ms. Evans's enjoyment of literary experimentation, as she dabbled in many forms of verse. Poems not assigned titles by the creator have been labeled according to their first line. All poems in the collection have been arranged alphabetically, with all drafts of each poem appearing in one folder for the poem title. Some poems within these folders have been signed and/or published under the name Julian Allen, Della J. Evans's pseudonym.

The final sub-series, Collected works, contains clippings and transcriptions of various poems, and were found mixed into Della Evans's own various writings. These are arranged alphabetically by the poets name. If there is no indication of the author, the works have been alphabetized according to their title.
