93,
if you have a local occult or metaphysical bookstore, then i recommend starting with some simple books (there is a small series, one cover is blue, the other orange, i forget the 3rd cover color in the series) entitled something to the efffect of "everything you always wanted to know about astrology" everything from planetary meangings, zodiacal sign interpratations, apsects, constructing charts, and so on.
crowley's book (General Principles... Astrology) is excellent though his "theory of complexes" really IS tuff, i think... and, from what i have observed, most people don't even open the book -- just throw it up on the shelf like a hard-cover collectors book. NOT. an excellent text book, but i do agree it needs some preparation and a good intermediate knowledge of astrology before diving in.
last but not least, i might mention that i think "sidereal" method is the bomb -- but most of the books that you might do an amazon search for with that phrase are really technical/heady/math oriented and not explanatory for a beginner.
most metaphysical/occult bookstores have good "beginner" astrology classes...
and here's a good online resources for free chart construction:
make sure to puruse all the available OPTIONS and i recommend clicking on:
free charts, then scroll down the list and click extended chart selection add a new person's data click here to show chart (natal or other wil appear)i believe if you scout around on the site, you can click various options for interpretation sets which will help you learn the basics of interpretation, also, if you are working with your text books/study guides by your side
good luck!
