LBRY is still going. You can delete odysee.com and lbry.org but you could still have access to the LBRY content via the client software. Download it while you still can at lbry.org.
Books
Apart from being a ThemTube replacement (which you don't need to rely on a server or run a server for) it can contain other kinds of files. Like old Books.
Type in the search bar an author. Then click on "Explore." After a second or two, you'll get a form where you should choose:
How Fresh: "All time"
Content Type: "Document"
Language: "English"
Price: "Free"
In there you will get eBooks of various formats matching that author or title. You can also upload books. If you don't mind scanning. Books that are in libraries or Archive.org are a good place to get digital copies of books. You can upload them for the future and posterity.
Now there are other things "Model" and "other". I couldn't figure out what "model" meant. "Other," includes things including zip files containing many books. I am not sure about "List" either.
The biggest problem for books is you need to know what specific title or author you're looking for. There is no browsing for anything other than video.
