UPDATE: Shelfari.com has a much better UI and is just as awesome. I’ve made the switch
I can’t remember whose blogger profile I was looking at but I saw a link for LibraryThing.com. I had created a personal web application at home to query Amazon Web Services to bring back all the information I could about my books. I did this years ago so that I could save it all to a CD and put it in my firebox in case of theft or fire/water damage. I also sent a copy of the CD to my renters insurance company. They were very surprised and actually starting querying their members for such items.
I like LibraryThing.com because it does everything I need. I can tag items for grouping and it has links to buyers, like Borders, Amazon, Barnes and Noble, etc. There are reviews and a “social” network to see who else owns the book or is currently reading it. You can catalog when you read the book and other great metrics. I like the comments section to put peoples names into, in case I loan the book out. Helps me remember where it is.
If you don’t have an account, it is almost mandatory as a nerd with a library. It’s a centralized way of remembering what books you own.
Yes, Safari Books Online is freaking awesome, but sometimes a normal book is what is needed. I know I can’t study with Safari (personal opinion). I use it more as a reference.
Check out my library here.
Special Note: They are in Beta and are a growing website. If the visitor load gets to big sometimes, you can’t view catalogs without signing in.
Matt D.: Also a cool program – Delicious Library I got a license via MacHeist, and while it’s not exactly what you’re saying, it lets you keep a catalog of all of your books, movies and games and uses AWS to give you up to tdate information (and download cover/case art) for each and displays them on a virtual shelf.
Jason Meridth: @Matt D. Awesome. Looks very cool. I prefer free tools that run on the web, like delicious.com for bookmarks, etc. Mainly because I’m cheap. :) I actually have a Mac Book Pro, so I’ll definitely check it out.
