I think there should be a BOOKS I WANT link for all libraries. It could be a place for people to request a book they want that the library system does not have. Or it could be a place to request an author that they have heard about. Then other patrons could vote on the choice. Or maybe you have a book in a series and you want to be sure the library orders the next one. Put in a vote!
Another cool thing to have would be the option to transfer the names requesting a title to the hold list before anyone else. This would encourage people to vote and let the libraries know how many copies they might need in the system. Not every library need purchase a not too popular book. Every library would know to order if the book was extremely popular.
Libraries should have a review function for books. The Roanoke Valley Libraries has a method of reviewing (0 to 5 stars) for the ebooks or audiobooks but no place for the bookbooks. (A bookbook seems to be the old fashioned paper books we all know and love.) You should be able to tell others that the author that you have always loved has written a stinker this time and not to bother.
There is a suggestion box/email option, but maybe I don't want a long conversation with a faceless library email. I just want to make my request and move on. One request gets you a place to tell others of your new find or to discover that you are a newcomer to this great author and to jump on the bandwagon. And then you are on the list! I can't wait for the call. My book is IN!!!!
