A few weeks ago, I went to a superb conference at AIM on Localization Techniques in Equivariant Cohomology. A frequent topic at that workshop was the lack of good surveys and references. Results from the 70s were being rediscovered, and no one knew where to start reading.
As a partial solution, the conference organizers have set up a wiki. There is a list of references, particularly on Schubert calculus and related problems, and of open problems. They are keeping editing restricted to selected users, but I imagine many of our readers would make excellent editors. Please take a look and, if you have anything to add, e-mail Rebecca Goldin or Julianna Tymoczko to become an editor.
