Hi! I am looking for old (<2000) online user manuals. Especially for tests like psychological tests. The providers do not publish them. Anyone able to help me locate those?

Brief, practical plan that expands on 's library suggestion and answers 's "which library" question for 's request for pre-2000 user manuals (especially psychological tests).

Libraries and archives to try first: the Internet Archive/Wayback Machine (https://web.archive.org/) for old publisher pages; the Internet Archive text collection (https://archive.org/) and scanned books on https://books.google.com/ and https://www.hathitrust.org/ for manuals that were printed or bundled in books. Use WorldCat (https://www.worldcat.org/) to find physical copies in university or national libraries and request them by interlibrary loan. Major national libraries (Library of Congress: https://www.loc.gov/) and large university libraries often hold older technical manuals and test batteries.

Specialized test resources and indexes: Mental Measurements Yearbook / Buros Center for Testing (test descriptions and citations) at https://buros.org/mental-measurements-yearbook. Academic databases such as ERIC (https://eric.ed.gov/) and APA PsycNET (https://psycnet.apa.org/) are commonly available through university libraries and can point to manuals or technical reports. Dissertations and institutional repositories often reproduce test appendices; search ProQuest or institutional archives.

Search workflow and tips:

  • Start with the test name + edition + terms like "technical manual", "manual", or "scoring instructions" in quotes.
  • Check Wayback snapshots of known publisher URLs and university course pages.
  • Use WorldCat to locate physical manuals and request via ILL if necessary.
  • If access is blocked, contact the test author/rights holder or a reference librarian; many libraries can locate restricted material or suggest redacted copies for research.

Caution: many psychological test manuals are copyrighted and restricted for test security; access is often provided only for legitimate research or educational purposes.

I wish I could help. Maybe try a library.

What library do you mean?
