1. I can use Library Thing for making up lists of books as I've demonstrated in the previous blog. It also might be useful for checking dewey decimal numbers or putting things in order. I don't do cataloging so this is not something I usually have to worry about.
2. I share booklists with patrons in a number of ways. ECRL prints up lists, which I hand out, such as Star Wars books, or Librarians choose influential book of the 20th century. I also sometimes make a display of books such as "Minnesota mysteries" or "books about the civil war". I print up best sellers or sometimes lists such as "best books of 2007 (according to Washington Post). There are also catalogs beside the patron search terminal for patrons who want to look for new releases. Lastly Novelist offers lists of "read-alikes" that I can use if I have a specific request from a patron. It seems like Library Thing would be a way to do a sort of "read alike" by accessing other books from certain lists.
