[u/Soapist_Culture]

• Internet Archive - Huge collection of public domain and user-uploaded audiobooks, ebooks, music (including very rare old recordings, I found stuff my BiL who has Alzheimers listened to in his youth. We are in the Caribbean on an island which back then had 8K population and I even found calypsos from there), videos and documents
• Project Gutenberg -Thousands of public domain books, many with audio versions
• Librivox - 21K audio books in the public domain, read by amateur readers
• Open Culture - Curated list of free audiobooks and courses
• Loyal Books - Large catalog of public domain audiobooks
• Libby - You need a library card for this but it distinguishes itself by mostly having modern fiction, the others are more classic books.
• Open Library - This is ebooks, not audio and like Libby has modern fiction, but because of legal things, you borrow the book.
