What to expect? We have over 230,000 books leveled that include atleast one of the four reading classifications (GR, GLE, DRA, Lexile). If we don't currently have the book leveled that you scanned, we will take note of it and try to get the levels/measures as soon as we can. In the event that you scan a book that we do not have, we can look it up from over 7 million book possibilites so you can still add it to your library or wish list.
What not to expect? At this time, it isn't realistic to expect that every single book ever published will be found. We do our best of adding the best content available and we are constantly expanding our database.
Note: Many books have several formats (e.g. paperback, hardback) and releases (e.g. original release 1998, new release 2010) that cause the same book to have multiple ISBNs. If the app can't find the ISBN of that particular version of the book, there is a good chance we have it and would be found searching by book title or author.
