I have a rather large cookbook collection (although I have certainly heard of larger ones, so I comfort myself with that). There are a whole stack of online library tools, aimed at cataloguing, lending to friends, social networking, etc. However, I really like Delicious Library, (mac only) which allows you to create an inventory of books just by scanning the barcodes with a webcam. And it pleased me again today, when I was able to publish my cookbook library almost instantly.
So, you can see my food library in all it’s glory here:
