Judging from the table of contents at http://www.elsevierdirect.com/toc.jsp?isbn=9780123851857 , it indeed looks like a collection of application notes.
If you still want to buy it, there is a discount of 30% mentioned in the last paragraph of http://www.elektronikpraxis.vogel.de/index.cfm?pid=856&pk=328069&nl=1&cmp=nl-101 (use Google Translate if necessary).
From the table of contents, it looks like that the book covers a wide range of analog topics: from power supply design to data converters to RF design. I'm sure this could be a very handy reference to the engineers.
Has anyone gone through a preview of the book?
As any Linear Designer knows, learning is not confined to the classroom. The classroom provides theory but this type of Text Book is the type that Designers like to have at the ready even if it is a compilation of application notes there is always information that "fills in the gaps" of our practical knowledge, and without a consistent updating of that knowledge you will fall behind. If you fill in one gap of knowledge over the app notes then the $90 is well worth the price. You can't put a price on practical experience and the art of Linear Design straight from the mind.
This book is definitely a Text Book. If you feel as though you have stepped out of the classroom then you have decided to leave your career behind you for all but the simplest tasks.
You can find it on Amazon for 5 bucks less and free shipping.
There it says it is based on application notes. But I'm sure it's not just a collection, otherwise, like said above, "why need to buy?".
Hopefully there is a lot of insight commentary.
