Developing with PDF - Leonard Rosenthol(2013)

 I normally do not write commentary on technical books as they are kind of associated with a period and as technology moves on new technology shows up. The books get outdated too soon. This one is about a technology that has almost seen maturity. PDF specification is pretty much a mature specification. Post release of the ISO-32000-1 published in 2008, the pace of development in PDF spect has become really slow. The PDF 2.0 spec is more of minor updates and not a major rewrite. The book is published in 2013. So very much current in that respect. The good part about this book is, it covers the high level features of most of the PDF specification. Text, Graphics, Optional Content etc. There are only countable books on PDF specification as such. Many books are available on the libraries that can be used to read and modify PDF specification documents. But purely a book that speaks of file specification is only countable few. From that perspective the book has lots of information look forward to. Secondly, being part of the Safari Online collection of Oreilly, most technical libraries will have access to the book. 

If you are looking forward to working on PDFs then this is a important book to keep. For advanced users of PDF specification is the book to refer to.
