The Quality Companion is a great book for lovers of comics history. It starts out with nine comics featuring heroes such as The Ray, Phantom Lady and The Human Bomb, with art by Jack Cole, Lou Fine and other comics luminaries, and then there is a detailed account of the history of the company. You may not have heard of Quality Comics (I hadn't), but it was one of the early comics publishers and the original home of Jack Cole's Plastic Man. Many of Quality's characters were eventually absorbed by DC. The book is well-written and detailed, and the comics in the front are at once cheesy and fascinating.
TwoMorrows makes the book, and most of its other titles, available in two formats, a hardcover print book and a digital version. The digital book is a PDF, which means it can be downloaded and read on any device, without any concern about the distributor disappearing and taking it with them. That also means it could be easily pirated, and there's a note in the front of the book telling people that if they downloaded it for free, they did so illegally. "Go ahead and read this digital issue, and see what you think," the note continues. "If you enjoy it enough to keep it, please do the right thing and go to our site and purchase a legal download of this issue ..." This makes so much sense that I don't know why everyone else doesn't do it.
It seems as if TwoMorrows has found a digital/print balance that works, at least for this type of book. The print edition is priced at $31.95 (marked down to $27.16 at the moment), and if you spring for it, you get the digital edition free. That's quite a reasonable price for a book like this. Even better, the digital edition is priced at only $10.95. The print edition will obviously appeal to collector, but for someone like me, who wants to read the book and have it as a reference, the digital edition is a great deal, especially with no DRM.
