WebSite: http://www.imagenet.org Electronic address: email@example.com MISSION STATEMENT The purpose of Solstice is to promote interaction between geography and mathematics. Articles in which elements of one discipline are used to shed light on the other are particularly sought. Also welcome are original contributions that are purely geographical or purely mathematical. These may be prefaced (by editor or author) with commentary suggesting directions that might lead toward the desired interactions. Individuals wishing to submit articles or other material should contact an editor, or send e-mail directly to firstname.lastname@example.org. SOLSTICE ARCHIVES Back issues of Solstice are available on the WebSite of the Institute of Mathematical Geography, http://www.imagenet.org and at various sites that can be found by searching under "Solstice" on the World Wide Web. Thanks to Bruce Long (Arizona State University, Department of Mathematics) for taking an early initiative in archiving Solstice using GOPHER. PUBLICATION INFORMATION The electronic files are issued yearly as copyrighted hardcopy in the Monograph Series of the Institute of Mathematical Geography. This material will appear in a Volume in that series, ISBN to be announced. To order hardcopy, and to obtain current price lists, write to the Editor-in-Chief of Solstice at 1964 Boulder Drive, Ann Arbor, MI 48104, or call 734-975-0246. Suggested form for citation: cite the hardcopy. To cite the electronic copy, note the exact time of transmission from Ann Arbor, and cite all the transmission matter as facts of publication. Any copy that does not superimpose precisely upon the original as transmitted from Ann Arbor should be presumed to be an altered, bogus copy of Solstice. The oriental rug, with errors, serves as the model for creating this weaving of words and graphics.
