I received the Kindle version (the Trilogy with the first 3 books combined) for my birthday and have read the first two volumes. I got the pdf versions here while they were on sale. This version (the PDF) is better in that it has the illustrations and footnotes at the bottom of each page. The Kindle version has footnotes at the back of all three books with no hyperlinks to/from the footnotes, which makes for difficult navigation. Both versions (Kindle and PDF) could benefit from an active table of contents and hyperlinks to/from footnotes. Overall the author shows excellent research into the history of D&D, with documented citations. There are a few typos throughout but not to the extent that it is unreadable. In fact, while very detailed, it reads quite fluidly. Also I found the author to be quite objective about the various people and events involved.

I love this series of books. I've read 1 & 2 and greatly enjoyed them. They cover the history of D&D from its beginnings, sharing stories that every gamer should enjoy: details of the early dungeon delves and characters who adventured under Castle Grayhawk and in Blackmoor.

Great book and series.Brings back fond memories of other similar history books of D&D that I have enjoyed.Please release other books in series in PDF format.PS all of your books look interesting.
