Primary sources or secondary

Dictionaries/encyclopedias (may also be secondary), almanacs, fact books, Wikipedia, bibliographies (may also be secondary), directories, guidebooks, manuals, handbooks, and textbooks (may be secondary), indexing and abstracting sources.

Data from an experiment is a primary source. Secondary sources are one step removed from that. Secondary sources are based on or about the primary sources. ... Tertiary sources summarize or synthesize the research in secondary sources. For example, textbooks and reference books are tertiary sources.

It’s either tertiary or primary (i don’t know thow it’s just my guess) goodluck!!
