Sage has just acquired this Open Access publisher. DOIs available but may have been metadata issues in the past (currently their journals are dead in CMS) but I bet this improves under Sage. http://www.la-press.com/
We’ve activated Lipid Insights which we believe is the last remaining former Libertas Academia title to transfer to Sage.
The remaining 12 appear to have been discontinued and are only available via third party repositories.
