I just noticed that this blog only links to the first edition of Selenium Simplified on amazon. This is particularly tardy and particularly poor marketing since the Second edition has been out for some time.
The 2nd edition is a refresh of the 1st edition. It doesn’t really have any new material, but has been updated so that all the old material works with the current versions of Selenium.
You can find it on Amazon (these are affiliate links):
And a bunch of other Amazon sites.
It is still available to purchase as an ebook directly from my company web site. http://www.compendiumdev.co.uk/selenium
