The letters, usually lengthy, from all the Allens to friends and relatives in the United States deal with the social, cultural and political conditions in China, as well as with the Allen's ministerial activites.

There are letters; WWW print-outs; email print-outs; artwork; audio cassettes; VHS tapes; DVDs; CDs; photographs; a scroll; a fan; printed ephemera; books; and a bust of Lao She.
