Cambridge University Press website mislabels and Astronomy text as an Astrology text. 
I was looking for open access open source freely downloadable and good textbooks to use in my future Astronomy classes.  The City Colleges require a very good text, but the supply of it to students in a timely manner hasn't been reliable as of late.  Over half of students in the City Colleges did not get books they ordered until the midterm.  

So I saw a page about books printed by Cambridge and the Open University.  Links on that website were broken so I went to search for them and found this.

Seriously?  Just shows nobody's perfect. :)  Not even the university known to science for  Newton and Hawking and many others.  Odds are this was done by a contractor working for the publisher issuu.com.  This is a common mistake people make even when enrolling in an astronomy class. 

So for the record while the study of star charts to predict lucky days or good days to plant is part of the long history of the study of the stars and planets in the sky, astronomy is not astrology. Astrology is not science it is a religion like belief system.
