Introduction At the Fourth International Reindeer/Caribou Symposium, held in Whiterhorse, Canada, 1985, Sweden declared it's intention to host the next International Reindeer/Caribou Symposium. A meeting with delegates from the participating countries was held and the Swedish offer was un• animously accepted. At the same meeting the experiences from earlier symposia were critically evaluated in order to achieve the best prerequisits possible for symposia to come. Some of the principal views declared were not to split the sessions in different meetings and in addition to con• centrate more of the scientific presentations on poster exhibitions and poster sessions. The Fifth International Reindeer/Caribou Symposium, held August 18-22 1988 in Arvidsjaur, Sweden, was thus in principal arranged according to the views expressed in Whitehorse. Arvidsjaur was chosen as site for the Symposium as it has long been a centre for reindeer herding and research activities. The excellent localities of the Norrland Dragon Regiment (K 4) put at our disposal and the hearty support of the township of Arvidsjaur and the Sami villages made the arrangements possible. In Arvidsjaur the USSR declared it's intension to arrange the next International Reindeer/Caribou Symposium to be held in 1991. The proceedings you now hold definitely close the Fifth International Reindeer/Caribou Symposium. Claes Rehbinder Secretary General Rangifer, Special Issue No. 3, 1990.
