The main site for the analysis of algorithms is the AofA page. There you find researcher's pages, conference information and sites of interest, a bulletin board, and research news.
In this course we use the book An Introduction to the Analysis of Algorithms and specially its continuation ``Analytic Combinatorics'' (in preparation) by Philippe Flajolet and Robert Sedgewick. We will also use several books by Don Knuth.
A similar course is happening this Winter in France. Check the wonderful page of the DEA Algorithmique, 1998-1999 (in French)
