**Projective geometry**: Robin Hartshorne, Foundations of Projective Geometry, Benjamin, New York, 1967. Recommended for general projective geometry for the purposes of matroid theory: treats all fields (and division rings) and abstract axiomatization, but without excessive attention to the special theory of nondesarguesian planes.

**Chordal graphs**: Martin Charles Golumbic, Algorithmic Graph Theory and Perfect Graphs, Academic Press, New York, 1980. Section 4.2 is recommended for basic information on chordal graphs, which he calls*triangulated graphs*.For the matroid theory of chordal graphs, especially the fact that G(Gamma) is supersolvable if and only if Gamma is chordal, see R. P. Stanley, Supersolvable lattices, Algebra Universalis 2 (1972), 197--217; MR 46 #8920.
