This is a very good app for accessing Pub Med. I found it both powerful and easy to use. It needs a little tweaking, though. It would be an excellent app if (1) you could sort the library by author, date, publication type etc. A multi-tiered sort function would be ideal; and (2) if you could create more than one library within the app itself or at least do so using Endnote. However, these are minor deficiencies that do not detract from the overall value of the app.
