General

In case you didn't know, Zotero 7 (beta version) includes native readers for HTML and Epub files! One issue I've always had with epub books is a lack of suitable software for reading them on computers (yes, I know about Calibre). Zotero 7 elegantly solved the problem.

• Project Gutenberg
• archive.org Two rather obvious entries, but the more I explore them, the more I get pleasantly surprised. They are true treasure troves.
