Query: Wait for the next edition

Although published in '97, this book is already quite dated - the Mars and Jupiter system maps are based on Viking and Voyager data. Given the cost of this book, I'd wait until an edition came out which integrated the Mars Global Surveyopr and Gallileo data. Also, the detail of some of the maps leaves something to be desired - most of the locations listed in the Gazeeter are not marked on the maps. Finally, too much expository text is included (in a large type with generous spacing). I would have prefered these pages to be filled with more maps, rather than text I could have found elsewhere.
