Internet Archive

The Internet Archive is a California-based non-profit specializing in digitally preserving (for free public access) old books, web pages, audio, and video. Services include Open Library and the Wayback Machine (with over 240,000,000,000 URLs).

Its terms of use prohibit copying offsite any material without written permission. It is probably fine for copying to Wikipedia but not to Wikia. "In particular, you certify that your use of any part of the Archive's Collections will be noncommercial".
