but we don't keep it up to date anymore because it is a manual process to find new publications and add their bibtex entries. Thus we mostly just point to google scholar for recent stuff.

  Verifying someone uses a particular part of PETSc (like GAMG) is difficult because you need to locate their publication and see if they mention it in the text (which often they will not do) or if they sent some email and mentioned using it. I've played with the idea of PETSc programs automatically sending back what solvers they use but for some reason some PETSc developers get paranoid about collecting this kind of information :-).

  Just count the number of email threads that have GAMG in the text and give that number to David Brown :-)
