The McCulloch Manuscripts are an important primary source of eighteenth-century historical documentation that to date have never been put into print in their original form.  This thesis is a critical edition and analysis of the 1,269-page, two-volume text originally entitled Examinations of Persons Under Spiritual Concern at Cambuslang, during the Revival, in 17-41-42, along with its accompanying documents and marginal annotations.  Compiled by the Reverend William McCulloch during the period of 1742-1749, and considered to be Scotland’s first oral history project, this collection of personal conversion narratives from subjects of the revival provides a unique perspective from which to understand the spiritually of both laity and clergy in eighteenth-century Scotland. Chapter One sets the Cambuslang Revival within its historical and local context, and chronicles the treatment given to the revival in prominent scholarly literature over the past two centuries. Chapter Two provides a description and analysis of the physical properties of the manuscripts, and of their distinctive nature and arrangement. Chapter Three details the editorial process utilized by William McCulloch in soliciting and interviewing narrative respondents, and in editing and compiling their narrative accounts in preparation for publication.  This chapter also proposes an interview framework utilized by McCulloch with the narrative respondents, and the distinctive role he played in framing and reporting the respondents’ experiences. Chapter Four definitively establishes the identity, role, and succession of each of the four clerical redactors who assisted McCulloch in preparing the Volume One for publication, analyzing their distinctive theological concerns - both individually and collectively - and their subsequent marginal annotations and revisions of the text.
