The only specific source type you will find in the library One Search is labeled reference. If that doesn't come up in your search, don't give up!
Check the top of your results list before you change any thing in the menu. Is there a Research Starter at the top? Many searches will, and if yours does, you're in luck. This is an article from a reference (tertiary) source that will give you helpful background on your topic and suggestions for further research -- keywords and additional sources, for example.
Tertiary Sources: Sources that assemble information from a variety of primary and secondary sources. The viewpoint is general and most removed from the original source.
Examples: Dictionaries, encyclopedias, databases, abstracts, directories, indexes, fact books, almanacs, guidebooks, manuals, textbooks.
