All the society's Proceedings from Session 106 (1963-1964) on are now available on the website. Links to the Proceedings can be found here.
The Proceedings for Session 151 (2008-2009) and later sessions are in the form of PDF text documents, which allow searching for text and copying of sections of text. In contrast, the Proceedings for earlier sessions are in the form of PDF image documents, which do not allow searching or copying of sections of text (although the images for individual pages can be copied).
Before Session 106, the society's Proceedings were published as part of the Transactions of the Geological Society of Glasgow. Society members can see the Transactions in the Lyell Collection section of the Geological Society's website. Instructions on how to log in to the Lyell Collection can be found here.
Our thanks are due to Brian Bell, who carried out the task of scanning all 31 issues of the Proceedings covering Sessions 106 to 150. (Some issues cover more than one session.)
