----------------------------Original message---------------------------- MapHist is indeed a new listserv and not a newsgroup. At moment, your mailbox will not become clogged with too many messages. One of the options, however, that we are investigating, is that you could receive MapHist in DIGEST form. This would allow you to receive a group of messages either daily or, i.e., when there are 10, 25, etc. messages in the cue. David A. Cobb Harvard Map Collection
