@thudfactor what are you using?
@thudfactor Love Calibre. I don't remember when I started using it - probably right after I got my 1stgen Fire in 2011? I've broken my collection down into general topic libraries (crafts, cooking, gen-non-fiction, etc) and use it to scrape fanfic from AO3. I'll have to check out Kavita.
and Yes, I have DeDRM installed ;)
@kismatt Calibre to manage metadata, Kavita to have an attractive web interface for browsing the books.
