For example, if it is a small library, read on an Android/iOS device, Jellyfin with JellyBook may be fine. If it is a large manga library already tracked on AniList, Kavita may be a good bet. If features like notes and highlights are important to sync across devices, something like Anx Reader with WebDAV might even be better.

i will start with jellybook to keep it simple. i didn’t know there was a jellyfin plugin for ebooks.

thanks for taking the time to share all that information
