Most of the material in Take Control of Your Paperless Office is still valid in OS X 10.8 Mountain Lion. However, please be aware of the following:

• Lion & Mountain Lion user library: The ~/Library folder, which I refer to frequently in the book, is hidden by default in Lion and Mountain Lion. To view it in the Finder, choose Go > Go to Folder, enter ~/Library, and click Go. Or, to unhide it permanently, open Terminal (in /Applications/ Utilities) and enter chflags nohidden ~/Library (you can reverse the command by using hidden instead of nohidden).
• Light Peak & USB 3.0: On p. 16 I refer to a new high-speed interface which at the time the book was published was still known by its development code name "Light Peak." That's now known as Thunderbolt, and it's standard on all new Macs. In addition, MacBook Air and MacBook Pro models released in 2012 have built-in USB 3.0 ports, and most likely future Mac models will, too.
• Dropbox pricing: I mention Dropbox on p. 17 and include its pricing. Recently Dropbox doubled the amount of data storage offered at each price point, so for example you now get 100 GB for what 50 GB previously cost.
• MobileMe & iDisk: MobileMe was discontinued on June 30, 2012, so iDisk is no longer available as a cloud storage destination.
• Hardware and software updates: Many new or updated scanners and OCR software packages have appeared since the book was published. I can't provide a complete list here, but be aware that today's options may differ from what's listed in the book.

In addition to these items, I've accumulated a fairly long list other things in the book that could use updating. So, I've been thinking about writing a second edition, and that will almost certainly happen sooner or later, although I can't yet say how soon or late.
