Information on Planetary Science PhD programs? APS has a catalog available with information on graduate school programs in physics. I was wondering if anything similar exists for planetary science?

So far I have been going through individual university websites and professor pages to find information which is time-consuming.
Catalogs of programs are a casualty of the internet age. Most schools would prefer to direct traffic to their individual sites, rather than have a short blurb in a larger publication—especially if it's something they have to pay extra to maintain.

As an example of this, the American Astronomical Association's Division of Planetary Sciences just has a compendium of links to school websites instead of a catalog. If a group like that maintains only a set of web links, I doubt there's a larger catalog out there.
