Hi everyone, If we can't have all the categories separated out in new books, another thought is to have the O'reilly books put up as a separate category. Usually, when the 100 books is acceded in terms of new books, it is usually because a bunch of O'reilly books have come through. If there could be a category, new from O'Reilly, that might solve the problem. Perhaps, the category could have the date of the most recent book
