This helps the understanding of the geography in Bible times contrasted with the 21st century. I had the standard edition (about 20 pages), loaned it out, and now needed a replacement. :-) I decided to replace it with the deluxe edition. The extra information is very helpful along with the option of being able to print from the CD for my classes. I also bought the pamphlet which is handy to carry all the time in my Bible case.
The great thing about this book is that it has a disclaimer saying it can be reproduced for classroom purposes. I was able to take it to a FedEx Office and Office Depot to make color copies of the maps for my Sunday School class.
