"The South Wales Coalfield Collection" (SWCC) is one of the largest archives of its kind in the UK and of international importance. This unique asset, however, has been under-used as a tool for medical history because, although the Collection has been catalogued, medical records are often 'hidden' and difficult to locate. "Medical Records for the South Wales Coalfield" is designed to make items of medical significance more accessible. Based on a screening of the Collection funded by a Welcome Trust Research Resources in Medical History Award, the volume will be a popular with academic researchers seeking to define viable projects and focus their efforts more effectively; teachers and lecturers wishing to put the SWCC to educational use and members of the general public interested in the medical and healthcare heritage of the Coalfield.
