Over the past few days I managed to read the “XPages Extension Library” book that has recently been published by IBM Press. The list of authors, contributing authors, technical editors and others reads like a who-is-who in XPages.

I’m very proud to know many of them and also had the chance to attend their sessions at conferences.

The book is very up-to-date, it targets the December 2011 release of the ExtLib, be it in the form of the Notes and Domino 8.5.3 Upgrade Pack 1 or as download of the ExtLib from OpenNTF.

The samples in the book refer to the teamroom template and the ExtLib sample application. So I recommend to download the latest ExtLib from OpenNTF as the download contains both templates.

The aim of the “XPages Extension Library” book is to collate the knowledge of the ExtLib and communicate it to the reader.

Although all authors have a different style of presenting content during conference sessons, the book reads in a very consistent way.

To get the most out of the book, you should at least be familiar with the XPages basics and perhaps, you already have read the Mastering XPages book that will give you a firm ground to understand the ExtLib.

“XPages Extension Library” from IBM Press is a must have, must read.

I strongly recommend that this book, together with Mastering XPages and XPages Portable Command Line Guide should be given to every developer starting with XPages.
