The free open source software Open Monograph Press (OMP) assists with each stage of the process of producing open access books and book series. OMP was developed by the Public Knowledge Project (PKP) at the University of British Columbia in Vancouver and published under a GNU General Public License. The software’s functions include external reviews, proof-reading, layout/production, and management of catalogues and book series. In addition to the local installation and administration, you can also have the software hosted for a fee (from USD 1500 per year plus additional fees of USD 125–175 for each published book as of 1 July 2015).
