Google Script: Enterprise Application Essentials: 
How can you extend Google Apps to fit your organization’s needs? This concise guide shows you how to use Google Scripts, the JavaScript-based language that provides a complete web-based development platform—with no downloads, configuration, or compiling required. You’ll learn how to add functionality to Gmail, spreadsheets, and other Google services, or build data-driven apps that run from a spreadsheet, in a browser window, or within a Google Site.
Heroku Cedar: 
This book will show you how to build a scalable and reliable high-traffic web application using Heroku Cedar as a platform. Originally available only for Ruby (on Rails), but now extended for many more languages, Heroku Cedar is a very interesting choice. The application we’ll build is a ping service, but with characteristics that meet the requirements of modern web apps: cheap (many checks), high frequency, low latency, and trending. With this application we’ll show you how to architect, build (using existing and custom add-ons), and operate a full-blown, high traffic web application. We’ll use different technological components, such as a good dashboard, efficient scheduling processes, and scalable data processing.
Head First HTML and CSS: 
Tired of reading HTML books that only make sense after you’re an expert? Then it’s about time you picked up Head First HTML and really learned HTML. You want to learn HTML so you can finally create those web pages you’ve always wanted, so you can communicate more effectively with friends, family, fans, and fanatic customers. You also want to do it right so you can actually maintain and expand your web pages over time so they work in all browsers and mobile devices. Oh, and if you’ve never heard of CSS, that’s okay–we won’t tell anyone you’re still partying like it’s 1999–but if you’re going to create web pages in the 21st century then you’ll want to know and understand CSS.
Learn the real secrets of creating web pages, and why everything your boss told you about HTML tables is probably wrong (and what to do instead). Most importantly, hold your own with your co-worker (and impress cocktail party guests) when he casually mentions how his HTML is now strict, and his CSS is in an external style sheet.
With Head First HTML, you’ll avoid the embarrassment of thinking web-safe colors still matter, and the foolishness of slipping a font tag into your pages. Best of all, you’ll learn HTML and CSS in a way that won’t put you to sleep. If you’ve read a Head First book, you know what to expect: a visually-rich format designed for the way your brain works. Using the latest research in neurobiology, cognitive science, and learning theory, this book will load HTML and CSS into your brain in a way that sticks.
So what are you waiting for? Leave those other dusty books behind and come join us in Webville. Your tour is about to begin.

2012-04-29: purchased the paper book in German as used book on Amazon
As o’Reilly/Germany doesn’t offer affordable e-book upgrades, I guess I will get the U.S. e-book as an “upgrade”
