Oh, did I mention it also includes levels through 36 for the base B/X classes? Yep, it does. As well as the spell lists to fill in any gaps through level 9 you might have.
New monsters and treasures too. Oh my!
Did I mention the price of this PDF? Free.
No bookmarks in this PDF, but at the price of "free" I can't really be all that picky.
Looks good at first glance with a definite B/X look to the typeface.
