This is a list of references for both versions - marked by the 1.5 / 1.6 logos.
The aim of listing references is to choose some that are found useful or that summarise Joomla! There are many detailed references at the foot of all the documents. Both versions are included here because it is useful to see what is available for both versions alongside one another.
As Joomla! becomes widely used, there are more books about it aimed at various levels of experience. It may seem strange to recommend books for an on-line application but the book has not died as a result of on-screen documentation. Studies have shown that people read differently on-screen and on paper, so it makes sense to use books alongside other resources. Here are some that enhance to the on-line or on-screen documentation.
*Ric Shreves, Joomla! Bible, Wiley, 2010. Comprehensive and practical. A reference book but with a lot of practical things, as well as nuggets of information. Good for developers but also useful for learners. It has some material about version 1.6 but was published for version 1.5.
*Cory Webb, Beginning Joomla! Web Site Development, Wrox Wiley 2009. One of the Programmer to Programmer series. Better for people with a bit of experience of computing in general and web sites in particular. But it has some good parts - including some detailed analysis of Template files.
*Ron Severdia and Kenneth Crowder, Using Joomla, O'Reilly, 2010. A descriptive book in the traditions of the O'Reilly publications. Not for beginners.
*Marni Derr and Tanya Symes, Visual QuickStart Guide: Joomla!, PeachPit Press, 2009. Helpful layout with a lot of screen shots and asides. Some experience of IT is needed but the book leads you along nicely and is written in a straight forward style.
None around yet specifically for 1.6
*Jennifer Marriott and Elin Waring, The Official Joomla! Book . This has a lengthy section on version 1.6 and covers the parts that have changed.
*Ric Shreves, Joomla! Bible, This has some extra comments in the text about differences in version 1.6, but does not have much detail.
There are some - to be added
