Sonny Software has introduced Reference Miner 1.0, a free Mac OS X application that lets you quickly and efficiently search Amazon for books and PubMed for biomedical literature. Reference Miner searches Amazon US, Amazon UK, and Amazon Germany for authors, title or keyword, and ISBN. All of the information available at Amazon, including user reviews and cover art, can be displayed. Reference Miner requires Mac OS X 10.2 or later, and as mentioned earlier, it is free.
