What I really like about this book is instead of jumping into a theoretical discourse, the reader is actually made to work on an example which highlights the concept being covered.
It is not everyday that one encounters a book which explains such a specialized but very useful subject as creating online maps. I found it [to be an] in depth book covering all the concepts related to implementing Google Maps while at the same time [stressing] a practical approach.
As always, you can find links to and quotes from previous reviews on this page. Enjoy.
