This study contains Astrology-charts including history data... It's better viewed on a PC or in printed A4 format, otherwise it's too small...
A normal "book format" would not get that right - beside that, once downloaded you can also print it and have all the "freedom" to make notes etc.
It contains 54 pages including cover page, list of content and 2 pages of credits and references.
