This workshop report has been published already (in a slightly different version) as a project deliverable (http://emodnet-biology.eu/sites/emodnet-biology.eu/files/public/documents/EMODnet_Biology_II/Deliverables_EMODnet_Biology_II/D4.4LegacyLiteratureDataRescueReport.pdf). In addition, an informal peer-review has been performed by a large number of co-authors who have actively commented on and improved this publication based on the first version of the report. We therefore believe that an additional pre-submission peer-review is not necessary.
