Upshot: A popular Erlang tutorial site becomes a book. Any downsides? Nope, unless you don’t like the style. But you won’t. Support the author!
I was a bit skeptical that there was another “Learn You Some…” book out there written in the same style as the Haskell book. But, as of this post, Learn You Some Erlang For Great Good! by Fred Hebert is one of the six & counting books recommended on Erlang.org. And while $40 seems pricey for an eBook, this one is a monster at 624pp (on my iPad, 954pp). I found the tutorial style very accessible. If you have some programming/scripting under your belt, I think you will too.
So why would you buy what is essentially the contents of the Learn you Some Erlang site? Maybe you work in a secure environment. Maybe you live with spotty or no internet as I used to. Or maybe you’ll be using the book ‘in the classroom.’ The bottom line is, if you seriously want to learn Erlang, and you match the skill level outlined in the book, then this book is for you.
The best part is, you can ‘test drive’ the book via the author’s web site. I recommend you buy the book, either from O’Reilly or NoStarch to get DRM-Free copies for all of your devices.
Aside: Peeking in ePub’s code.. Take a wild guess who assembled the book for NoStarch. Yup, O’Reilly. So you know the ‘build quality’ is there.

Disclosure: I received the eBook download(s) from NoStarch for review purposes.

Upshot: It’s a “Cookbook.” Truth in advertising, you’ll find recipes. Upsides? It’s from O’Reilly. So the quality’s there. Any downsides? Windows-centric, probably not meant to be read cover-to-cover.
Upshot: As this is an ‘Up & Running’ book, there’s no wasted time. Upside: All the info, VERY concise. Any downsides? You’d better be intermediate, as with other ‘Up & Running’ books, this is a dense crash course.
Upshot: Do you need background or even a refresher in Web Design? This is your book, now in 4th edition goodness. Upsides: Lots. A full survey of the current state of the web, including HTML5 & cutting edge CSS/JavaScript. Any downers? Not really.
