Everyone knows that Plex is great for movies and tv shows.
Does anyone know if there is anything like that for books in pdf/epub/mobi/etc ?
[Login to see the link] is a top notch app for managing your e-books collection.
I second what [Login to see the link] said. Calibre would work for that. You can host your books using Calibre-web.
Google Play books is another alternative, but the play store version isn't as good as the version available for Chromebooks.
