During the winter of 2009-10, archive material from Alun Thomas (group Secretary 1966-1989) was given to the Group, prompting the opportunity to compile 50 years of the Group’s activities. This was completed in 2015. The full fifty year archive comprises, in 20 sections, original paperwork, a box with a copy of virtually all the Group’s publications, a roll of the posters prepared by the Group, two DVDs containing all the computer files prepared from this material.
For each of the 20 sections, a digital compilation has been prepared, in .pdf file format. 17 of the 20 sections is available here on our website as searchable pdf's, 3 of the sections having data protection issues.
Up to around 1990, the compilations have been based mainly on Alun Thomas’s papers. For 1990-2010, further material has been added from the SWGA papers and digital archive of secretary Geraint Owen (1990-2009) and secretary Lynda Garfield (2009- ). Other members of the Group have also contributed: photographs, publications, newsletters, membership cards, Treasurer’s papers, Programme Secretary’s papers, parts of the Welsh Geological Quarterly and scans, 50th Anniversary material, and more. All are thanked for their contributions.
