This paper is a revised version of that published by the Scottish Georgian Society under the same title in 1969. As before, I have endeavoured to list the main documentary and printed sources available for the study of Scottish architectural history without in any way attempting to compile a complete bibliography of Scottish architecture. The arrangement of the text follows that adopted by H. M. Colvin in his Guide to the Sources of English Architectural History (Pinhoms, 1967) to which reference should also be made. I should again like to acknowledge the assistance given to me in the preparation of this guide by various friends and colleagues, and in particular by Dr A.L. Murray, of the Scottish Record Office.
