Published by the Canadian Global Change Program of The Royal Society of Canada. CIGA is a valuable listing of Canadian contact persons for international activities and research related to global environmental change. The compendium also contains a matrix illustrating the focus of each activity, an extensive list of acronyms, and the addresses of many organisations around the world with mandates relevant to global change research. CIGA will be updated every two years, with more frequent updates available on-line through the CGCP Internet gopher. It is currently available free of charge on a 3 1/2″ floppy disk and will be made available as an ftp file and as a WAIS-indexed file via the CGCP
