PLoS Currents FAQs - a knol by PLoS

"Works submitted to PLoS Currents will be screened rapidly by a group of expert moderators to exclude material that is unsuitable, but will not receive in depth peer review that is required before publication in the PLoS Journals. For PLoS Currents, the process of authoring, submission, moderation and commentary will rely on the Google Knol software. There are also no a priori restrictions on the size, format, style or content of a contribution submitted to PLoS Currents (except relevance and potential value)....There are currently no publication charges for PLoS Currents. However, it is possible that we will introduce a small publication charge in future to cover the running costs....We intend PLoS Currents: Influenza to be the prototype for additional PLoS Currents site."
