Five journals with free (or recently extended) online trial periods were recently announced; online content includes full text, figures, and tables. The American Association of Cancer Research's Cell Growth & Differentiation journal will have an extended free trial period, now free through June 26, 2001. Online full-text content begins with the January 1999 issue; abstracts are online from 1990 (inaugural volume). The journal is published in conjunction with Stanford University's HighWire Press.
