Offline Library
In light of all the Ao3 issues lately I'm gonna throw this up as something people should consider doing. Make your own library of your favorite fics and any you might like to read in the future/are currently reading.
How do you do this? To start: Calibre & ReadEra app
Calibre is a free ebook management software, available on windows, mac, and linux - but also comes in a portable version you can put on a flash drive. Ebooks are very small files, 100s of fics can easily take less than 1GB of space. You can create categories for everything and all the tags on the fics will stay attached to them. You can download directly through ao3, or you can use the browser extension Ficlab which can make the process a little quicker, plus give you a book cover(or you can add your own cover). Epub or Mobi format is best.
ReadEra, is a free reading app with no ads that you can tell to only access a single file where you keep your ebooks. It's open source and the Privacy Statement and Terms & Conditions are very short and easy to read. You can transfer files from Calibre to your phone, but this is also a good option if you don't have a PC to use Calibre. You can make folders to organize all your fics.
Quality of life plugins for Calibre: Preferences > Plugins > Get New Plugins
Look up: EpubMerge, EpubSplit, FanFicFare, Generate Cover (restart calibre once you've added them all) Fun fact, with FanFicFare, you can download new chapters to update fics that are currently in progress directly in Calibre instead of having to open up ao3.
Also, to be clear - back them up for yourself only, don't you fucking dare repost them anywhere.
You can also backup Kindle books (and you should) with Calibre, though that's a bit more complicated; instructions under the read more
