I enjoy listening to books in mp3 format and I was wondering if there was an applescript that would remember where I left off. This applescript would act like a bookmark which could automatically go back to my last position in the book. Is there such a thing? And would it be possible to develop one?
Check our ScriptBuilders section for iTunes. There is an AppleScript in that section that does as you are requesting, see Bookmark (for iTunes) 1.0, by Graham Nelson.
There is also a very large archive strictly for iTunes on Doug’s Applescript for iTunes page. He also supports a forum for AppleScript in iTunes at the iPod Lounge site.
