1979 PREFACE

The Freshwater Biological Association was founded on nth June 1929 and will thus celebrate its Jubilee in 1979. The main object of the Association, as set out in its Memorandum of Association, is: "To promote the investigation of the biology (in the widest interpretation of the word) of the animals and plants found in fresh (including brackish) waters". These investigations have been carried out by the scientific staff of the Associa- tion, and students and visiting researchers working at its laboratories. The results of these researches have nearly all been published, mostly in scientific journals but some in books or in the Association's own Scientific Publications or Occasional Publications. These papers and other publications have been listed in the Annual Reports and also in the annual sets of collected reprints bound for exchange with other libraries, but we have thought it appropriate, in our jubilee year, to issue a full list of all the publications emanating from the Association's work and its laboratories of which we are aware and which had been published up to January 1979. The total number of publications in this list is 1488+122 translations. They include work in several different fields of biology, but most have an ecological approach and others are on physical and chemical aspects of the freshwater environment. Taken together they provide the best measure of the Association's achievement as a research organisation in the first fifty years of its existence, and the principal way in which it would wish to be judged.
