As tertiary sources, encyclopedias, dictionaries, some [[textbook]]s,<ref name="umd" /> and [[compendium|compendia]] attempt to summarize, collect, and consolidate the source materials into an overview without adding analysis and synthesis of new conclusions. 

[[Bibliographic index|Indexes]], [[Bibliography|bibliographies]], [[Concordance (publishing)|concordances]], and [[Database#Research|databases]] are aggregates of primary and secondary sources and therefore often considered tertiary sources. They may also serve as a point of access to the full or partial text of primary and secondary sources. [[Almanac]]s, [[guide book|travel guides]], [[field guide]]s, and [[timeline]]s are also examples of tertiary sources.

[[Wikipedia]] is a tertiary source.<ref>{{cite web |title=Primary, Secondary, and Tertiary Sources |url=https://crk.umn.edu/library/primary-secondary-and-tertiary-sources |access-date=19 April 2023 |publisher=[[University of Minnesota Crookston]]}}</ref>
