Volume 2 consisted of parodies of famous illustrations from literature, and Volume 4 carried reproductions of cave and mining woodcuts from the 19th Century. In the present index, no reference to any individual G.S.G. member, past or present, has been included, and all matters of a purely internal or domestic nature have also been omitted. Not a great deal of cross-referencing has been done, so readers are advised to look for specific subjects under different headings relevant to that subject. Cave names are catalogued under true name, with suffixes such as Pol, Uamh, Gouffre etc. Names are listed textually, so entries may be found under both Gaelic and English renditions.
All entries refer to Second Series only.
Illustrations and survey entries are underlined. The index is in three parts. List of contents. In section 2, brackets indicate unsigned work by the particular author. The first came out as a supplement to Vol.
