Hi, list: If you haven't seen it already, take a look at the International Astronomical Union's site at http://www.iau.org/. If you dig for it, you can find a lot of information there about subjects related in one way or another to meteoritics, but especially see the page for Commission 22 (Meteors and Interplanetary Dust): http://aci.mtadot ca/TheUmbrella/Physics/Meteor/IAU22/.
