The 2017 edition of Totality: eclipses of the sun is listed under the Eclipse tab. However, the first edition of the guide was produced by Mark Littman and Ken Willcox for a July 1991 eclipse where the path of totality passed directly over the Big Island of Hawaii, then crossed Mexico, continued down Central America through Colombia and into Brazil. Fred Espenak was added as a contributer for the second edition, which was released in conjunction with a 1999 eclipse that crossed Europe, the Middle East and India. The third edition, out in 2008, added new chapters on eclipses between 2008 and 2010 as well as a chapter on the 2017 “All-American” eclipse. It was followed, in 2009, by an “updated” third edition which pulled the chapter on a now-passed 2008 eclipse for one covering 2012 to 2016. If one is curious to trace the modern practice of eclipse chasing, examining these evolving versions of Totality may prove interesting.
