TITLE: Affine Spaces and Affine transformations
QUESTION [5 upvotes]: Can anyone please recommend a book that describes Affine Spaces and Affine Transformations? Many books i saw described it very briefly. Can anyone please suggest a book that deals with it in detail?
Thanks!

REPLY [3 votes]: You can read Jean Gallier's book Basics of Affine Geometry, which is available from Springer.  Gallier also has some notes on this topic available for free download at
ftp://ftp.cis.upenn.edu/pub/papers/gallier/geomath2.pdf and at http://www.cis.upenn.edu/~cis610/geombchap2.pdf.
