This is what we have needed in the biblioblogosphere for a long time. Have you ever been looking for a blog post you read a while back, but you don’t remember who wrote it or exactly when? All you remember is the topic and that isn’t going to get you too far. Well, things in the library blogosphere just got a lot easier to find. LISZEN allows you to search over 500 library blogs using Google’s new Custom Search service. You can also install LISZEN as a browser toolbar (thanks to Kevin Yezbick). Thanks to Garrett Hungerford for taking the time to create such a useful tool for the profession!
