TITLE: Reference request in contact geometry.
QUESTION [5 upvotes]: I am looking for an introductory book to contact geometry, as clear and detailed as possible.
Thank in advance.

REPLY [7 votes]: Hansjörg Geiges's Introduction to Contact Topology seems to be the only textbook-style reference on Contact Geometry. (At least it was three years ago, but I'm unaware of a more recent book with this kind of ambition).
