Robertson, Neil (ed.) et al., Graph structure theory. Proceedings of the AMS-IMS-SIAM joint summer research conference on graph minors held June 22 to July 5, 1991 at the University of Washington, Seattle, WA (USA). Providence, RI: American Mathematical Society. Contemp. Math. 147, 591-600 (1993).
A brief survey of forbidden minor characterizations for graph classes of treewidth at most three is given. Techniques for finding small sets of minimal forbidden minors are discussed.
