Plans are being prepared for the 5th Edition of the Directory of paleontologists of the world to be published by the International Palaeontological Association in time for distribution at the 27th International Geological Congress, Washington, D.C., 1989. Formal notification and timings will be issued in 1986; requests for information from individual paleontologists and paleontological associations will be distributed throughout 1987 and 1988 with a deadline for receipt of data of December 1988; computerization of data will proceed through 1988 with final preparation of text and publication during 1989. It is intended to provide the most complete listing possible of all of the active paleontologists of the world. We expect to obtain data from paleontological societies and organizations of all kinds as well as from individual paleontologists. Paleontological groups and individuals who are not members of IPA or who do not regularly receive the journal or newsletter of an IPA Corporate Member, should contact the Directory editor or IPA secretariat during 1987-88 to insure inclusion in the Directory. Suggestions and advice from all interested parties are welcome.
