Erlangen, Germany--Friedrich Alexander Universitat, December 2, 1981

Habermann traveled extensively to address CMU Software Engineering Institute (SEI) funders such as the U.S. Department of Defense Advanced Research Projects Agency (DARPA); scientific organizations such as the National Science Foundation (NSF); administrative panels such IBM's Science Advisory Committee (IBM-SAC); industrial-academic conferences on computing; and university audiences in Distinguished Lecture series or through visiting committees and advisory boards. While he often gave presentations identical or similar to those he ordered filed under Talks, his purpose in creating a Trips file category was to have readily available the names, addresses and phone numbers of contacts made during these engagements. The original file folders frequently contained the engagement contacts names for quick reference; normally these are recorded in the foldered documents. Secretarial notations of cancelled engagements and other circumstances are bracketed [] within folder titles. The Trips series comprises two boxes of material. Incoming and outgoing correspondence regarding Habermann's multifarious travels is largely arranged in the engagement-specific Trips series folders, but after secretarial method may also be found in the Correspondence series. Note that correspondence relating to a trip may extend for as long as years before and after the date of the engagement recorded on the file folder. The series is arranged chronologically, inverting Habermann's reverse-chronological ordering.
