I love my ereader [Kindle] and use it all the time. I've used Calibre since day 1 for my libary management, and find it a fantastic tool!!
I'm hooked on audiobooks as well. I use them when I'm being active [pretty often] on my Sony Walkman. I know Calibre is set up for managing 'written books', but is it possible there is something happening to add the 'mp3' of audiobooks into the Calibre library?
Yeah, I know, I'm probably asking a bit much, but if I don't ask, I won't know, eh
PS: Sorry if this is not the correct place for my question, but I couldn't find anything else.
