The first 200 books are free after that there is a $10 lifetime charge. The best thing about this is that you only have to enter the ISBN or ISSN code on the book. If it does not have that, the site links to 30 different libraries to pull partial title and author info. These include Japanese so that there is support for it. The usual info is available in table form or individual forms, but as an added kicker it will pull a picture of the cover off of Amazon.com.
