Librarians

From what I have experienced in my high school and in public libraries, librarians have an extended amount of work. They not only sign in and check out books some are also in charge of doing check in and check outs and organizing the returned and misplaced books in the right shelf. Also, they need to set up accounts for new students who might need to sign out books or log into the computer lab. They're there to order new books and help find books and set up systems to find books easily. Librarians do all this and save a lot of valuable to students who only have brief amounts of time to complete long projects. Most importantly they are there to teach you how to use researching tools and answer any questions asked regarding their library. I think librarians already do as much work as they can but if they had a Ipod touch kind of device for students to check in and out books by themselves it would be cool and less work. In the future I picture libraries that have a mechanism where you have find the book and an automatic machine will bring it out of its shelf and brings it to you. If this does happen library structure will be tall with shelves hanging or suspending in the roof all over the place. I think this might only happen if people start being active and walking up to get a book from a shelf in the library is not their only exercise.
