Launched in September 2007, the PLoS Hub for Clinical Trials collects PLoS journal articles that relate to clinical trials. The Hub is a destination site for researchers to share their views and build a dynamic, interactive community. Currently, the PLoS Hub for Clinical Trials is in a beta version which features articles originally published in PLoS Clinical Trials, along with clinical trials articles from PLoS ONE. PLoS launched this resource in beta to allow the scientific community to help shape this and future PLoS Hubs. In the future, PLoS Clinical Trials will expand to include articles from all the PLoS titles that publish clinical trials. It will also feature open-access articles from other journals plus user-generated content.
