This product is one the best world building products to ever come out of TSR. It's a groundbreaking work of RPG history, and a fun read, so 5 stars for that up front.
The map is in one piece which is nice for mark-up if you're running a city game. The scan of the book is decent. It's mostly searchable by text and the Table of Contents entries are clickable. The columns are a little crazy so, copy/paste is a pain and not really worth it if you can bang out more than 40wpm. My star rating is as follows:
-1 No Print-on-Demand. This product begs for it. Please, work it out however you can.
-1 Including the map with the text in one file forces you to do zoom tricks to see the text well, and the book and map are designed to be used together. In the future consider providing these as seperate files.
+1 Clickable TOC as this is a really useful feature.
[4 of 5 Stars!]
