The National Archives is primarily a repository of federal government records. Unlike the Library of Congress, it does not collect literature for the sake of collecting literature. If you are trying to locate a book, the Library of Congress is more likely to have it.
Do you have any additional information about why you think it is at the National Archives, and if so, in what context the poems may have come into federal custody? For example, were the poems created in the course of her employment by a particular federal agency, or did she mail the poems to a particular federal official and those poems were retained in his correspondence files?
Also, I know you say you don't have dates, but can you at least provide a rough date range? If nothing else which years she was alive?
Dear Ms. Sanders-Williams,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog, the National Archives Library Information Center (ALIC), the LIbrary of Congress, and Hathitrust, but could not locate any records authored by Darlene Duff Rollison. We suggest that you contact your family members or Darlene Duff Robinson’s local library for any information regarding these poems.
We regret we cannot be of more assistance. Best of luck with your research.
