Covers of biology community newsletters; here, Arabidopsis Newsletter (1990) and Worm Breeder's Gazette (1990). These, like Drosophila Information Service and many others (see [3] for a partial list), helped to adjudicate community membership and mediate sharing and ownership. They typically communicated technical innovations, nomenclatures, community news and lists of which (living) stocks could be obtained from what laboratories.
