Five years ago we launched a major theatre research project, “The London Stage 1800-1900: A Calendar of Performances,” with the ambitious goal of recording every important fact about every performance on the London stage in the nineteenth century. Our experience with archives, source materials, participants, and funding agencies has suggested that a reorganization and redefinition of the project, with identification of discrete phases and segments of the work, will make it more manageable and attractive, even if this means a delay in the completion of the full daily calendar that remains our ultimate goal.
