All, I recently bought the new 6th edition of the HEMA Kimberley Atlas & Guide.  I discovered a number of errors in the index, pointing to wrong map coordinates.  One or two of these were only one grid square off and could probably be explained, but for one the index pointed to the wrong map and had grid square coordinates wrong as well, so nothing about the index data was anywhere near correct.  I reported these and have been advised by HEMA that they have regenerated the index, and they sent me a PDF file with an updated one.  For anyone with or buying that book, you might want to contact them and ask for the updated index file.  Otherwise I found it an awesome information & planning resource, and am about to head off for my first but hopefully not last expedition to the Kimberley (well, under 4 weeks to departure now).

Safe travels
