[Paperbackstash]

I use Goodreads to shelve everything. When browsing used bookstores especially, I have to sometimes double-check to see if I don't already own a book. Scanning the book ISBN or manually typing it brings it up (or not) on my shelves, and has saved me from duplicate purchases. I have custom top shelves on there sorting everything from Kindle Unlimited, TBR (by genre), read, wishlist (by genre), Audible wishlist, Library-audio, etc. Once something is read, it goes to the read shelf, and a non-exclusive shelf dictates what format it's in.

I also use a large book spreadsheet to track reading and reading cycles (in progress) for my own amusement and back-up. Still much work to be done, I'm trying to go back to at least 2011.

I use Calibre for PC with digital e-books as well, wish there was an easier way to sort and store Audiobooks with the program also. I don't have a huge Audiobook collection, but it's something I'd like to sort and make notes with, so right now I've been using my spreadsheet with quick notes (kind-of). Browsing from Audible's library feature is tedious, and of course only shows books you've obtained through them. I like to sort a bit with Calibre but I don't find it useful on the run since I don't

With reviews I do Goodreads and my website, but it seems like I'm 6 months behind on reviews anymore and not into it as much. If something happens to my review at one site, it helps to back it up from the other. I have a LibraryThing account - I like that website for groups and profile features, but I find it too tedious for book cataloging.
