# 19 Discovering web 2.0 tools
I enjoyed this session and looked at 3 different sites. Firstly I looked at Biblio.com a book search and market site for out of print and rare books. I thought it would be useful for finding that special book you have lost and would like to find again. Unfortunatley, I couldn't remember enough detail on some of the books I wanted to see if were still around, good success with others. The second site I visited was Yelp, but this was american and while I had a quick look around, didn't have a lot of relevence to me. Thirdly, I looked at One Sentence, I loved this site, is of little use but it made me laugh and if you wanted to, it could probably make you cry. It has links to more on each sentence. I have included the address here as I think many would enjoy it and may find unexpected uses for it.
