The following report gives an account of research undertaken by a working group at the American Insitute of Mathematics investigating the mod p local Langlands correspondence, during the workshop ``p-adic representations, modularity, and beyond'', held at AIM in February, 2006

In 1999 the IAS/Park City Mathematics Institute was devoted to arithmetic geometry.
I gave an informal lecture there introducing the subject of p-adic modular forms, a
write-up of which has been incorporated as an appendix to Fernando Gouvea's lecture
notes from the Insititute. Here is an early draft of this appendix (it is missing figures
and some corrections).
