I have heard libraries rave about Apollo's Reserve Express. What is it?

Apollo's Reserve Express (TM) lets patrons subscribe to their favorite authors. When new items from Reserve Express authors are added, staff places all subscribers on the reserve list with two clicks! That's it! (Yes, the subscriber list is randomized before being added to the reserve list). Patrons no longer need to hound the library about when new titles are coming in or worry that they'll miss one. And there are no handwritten lists needed to keep track of what patrons like what authors. Delighted patrons. Delighted staff. It's a wonderful thing.
