The PDF is indeed of marginal quality, though not nearly as bad as previous comments led me to expect.

The contents more than make up for the rough quality of the scans. Rather than simply a collection of of modules B1 through B9, you get a low-level campaign using reworked elements of the nine modules and integrating them into the Grand Duchy of Karameikos (Gazetter 1).

This reworking, however, does mean some elements have been omitted, most noticeably the keep from Keep on the Borderlands (the Caves of Chaos feature, though) and little if any of B1. Others (B3, B6, B7) are largely intact.

All in all, this gets 5 stars for its own content, though only 2.5 if you're looking for B1 through B9 in their entirety. For PDF quality, it rates a rather charitable 2, legible, though murder to print.<br><br><b>DISLIKED</b>: PDF not of the best quality.<br><br><b>QUALITY</b>: Acceptable<br><br><b>VALUE</b>: Satisfied<br>

Haven't seen these rules in decades, so it's great to get my hands on them again.

On screen, the pages are dun colored but printed white, so I didn't have any of the printing issues mentioned by others.<br><br> <b>LIKED</b>: Mass combat and domain management rules are some of the best ever devised.<br><br><b>DISLIKED</b>: Nothing.<br><br><b>QUALITY</b>: Excellent<br><br><b>VALUE</b>: Very Satisfied<br>
