Modernist lab
The Modernism Lab at Yale provides links and source materials and chronologies for the study of the early years of modernism. It seems to be set up to support a growing cluster of courses on modernism at Yale. It's not clear yet how much of interest and use it'll be to others, but at least there are a number of links to the full texts of modernist works of that period, and good (if so far partial) chronologies.
