The process of authoring, reviewing, and publishing scholarly articles remains an expensive, time-consuming process that can require significant up-front investment and technical expertise. Coupled with lengthy review processes this can create delays of up to a year before new scientific findings are published. Annotum, a new, open-source, open-access authoring publishing tool based on the WordPress content management system, builds on the earlier work of the Public Library of Science's Currents publication and provides an easy-to use alternative to existing publishing systems that supports very rapid expert review and professional online publishing. Annotum is a production of Solvitor LLC with heavy lifting provided by Crowd Favorite, and special thanks to: Google, PLoS, NIH/NLM/NCBI, and Automattic. Annotum is free.
