Harris, J. Rendel. "Transcription of the Text." The Teaching of the Apostles, newly edited, with facsimile text and a commentary, for the Johns Hopkins University, Baltimore, from the MS. of the Holy Sepulchre (Convent of the Greek Church) Jerusalem. Baltimore: Publication Agency of the Johns Hopkins University, 1887, 1-10.
Harris introduces his edition of the Didache by discussing the importance of making a photographic record of ancient manuscripts, and acknowledging the effort and collegiality which allowed Johns Hopkins to obtain and publish photographs of the Didache manuscript. His text is intended primarily to summarize scholarship between the original publication of the text in 1883 and the publication of his book in 1887.
The first chapter is taken up with a transcription of the text. He provides transcriptional correction notes in the margin and through footnotes (Harris 1887, 1-10).
