The National Heritage Science Forum (NHSF) blog posts for the month of May have continued to be a “Spotlight on SEAHA” in preparation for the upcoming 2nd International SEAHA Conference in June 2016. Lucie Fusade (University of Oxford, School of Geography and the Environment) described her research in “Mitigating dampness in historic buildings: when ancient techniques and science come together” on May 19th. And the final May posting was by Natalie Brown (University College London, Institute for Sustainable Heritage) on “Collection Surveys as Part of Library Document Supply Chain.”
