I thought I had a lot of audiobooks until I read some of the entries here...now I'll have to look at my actual numbers when I get home
I have a variety of audiobooks from all over the place as well. I keep them in a folder (and backups) with sub-folders based on Author and series (if applicable). I keep a catalog of my ebooks in Calibre and have a custom column that I have been saying I am going to add a tag to (like Audio(mp3), Audio(xyz)) but i recently found out about the polish feature and have started completely overhauling my ebook collection and this got pushed to the back-burner. But to embed tag/image/information to the audio files I use a program called
TagScanner and I listen to them on my ipod (less and less now) and my Android Phone using
MortPlayer Audiobooks, especially when driving, cleaning, running errands.
Now to see how many i actually have
ETA: looks like I'm in the middle with 250 confirmed and approx 25 or so that i just realized need to be cleaned to my liking
