I have a number of books on my iPad by a particular author.
On the AUTHORS page the number is accurately shown.
However, when I select that author, only one of his books is listed.
Where did the rest of the books go?
Not sure unless we could see the author's list. One thing I'd check is that the author's name is spelled exactly the same in all the books. The code to count the books may be different than the code to list them... one could be more tolerant of capitalization or somesuch??
