In 2003, the Public Library of Science (PLOS) began a rather ambitious and most welcome project that would effectively offer unlimited access to the latest scientific research by creating a number of high-quality, open access journals. The first journal, PLOS Biology was launched three years ago, and since then, PLOS has created several additional journals dealing with medicine, computational biology, and genetics. Visitors should feel free to browse through back issues of each journal, and download various articles that might be of interest. Along with access to these peer-edited journals, users should also take a look at their “News & Events” area, which contains information about upcoming conferences and events sponsored by PLOS and other scientific organizations and professional groups.
