Special Collections

The Special Collections Department in the Morris Library includes many primary sources. Consult with the staff to identify appropriate sources. Manuscript collections may not be in DELCAT.


From Off Campus

Most Library online resources can be accessed from off campus by current UD faculty, staff, and students. When using links on these pages, you may be prompted for your UDelNetID and password. Please report any issues you encounter while accessing Library databases, e-journals, or e-books.


What Are Primary Sources?

Primary sources are first-hand accounts of topics or events. They provide firsthand testimony or direct evidence.

Primary sources include diaries, speeches, letters, manuscripts, memoirs, autobiographies, records of governments or organizations, and published materials (books, journals, newspaper articles) written at the time of an event or issue. Primary sources may also include photographs, tape recordings, oral histories, and maps. In literature, an original work such as a novel, poem, short story or play is also considered to be a primary source.

Secondary sources are accounts of the past written after the event. They are often based on information found in primary sources. They interpret or analyze a particular event. Secondary sources include textbooks, encyclopedias, and literary criticism.

  • It is often a good idea to review the secondary literature first to gain an understanding of the key players and events associated with the topic.

  • Primary sources are much easier to find with specific names and events for searching.
