A new volume by Brill has several articles oriented toward the Pastorals:

Studies on the Paratextual Features of Early New Testament Manuscripts. Edited by Stanley E. Porter, Chris S. Stevens, and David I. Yoon. Texts and Editions for New Testament Study. Leiden: Brill, 2023.

Solomon, S. Matthew. “Segmentation and Interpretation of Early Pauline Manuscripts.” (pp. 123–45).
“Manuscripts from the ancient world had less stereotyped formatting rules than books and media today. Unfortunately, some of these features are greatly underap-preciated for their potential interpretive value. In this paper, attention is given to how scribes of the Pauline corpus used spatial segmentation for their distinct pur-poses. The aim is to provide insights into how these scribal choices may influence the interpretation of certain texts, including 1 Cor 7:39, 14:33, Eph 5:21, 1 Tim 3:1, and Phlm 7. Finally, the chapter concludes that paragraphing and segmentation in the ancient world are quite different from today, and some of these differences are exe-getically significant.”

Tommy Wasserman and Linnea Thorp. “The Tradition and Development of the Subscriptions to 1 Timothy.” (pp. 172-201)
“This study examines the textual tradition of the subscriptions to 1 Timothy, proposing a typology based on a collation of 415 Greek manuscripts. The authors discuss the traditions about 1 Timothy reflected in the subscriptions in relation to other paratexts, internal evidence, Corpus Paulinum, Acts, and the wider church history. The creation and elaboration of subscriptions to Pauline letters, shaping the way they are read, not only satisfies human curiosity but serves to further authenticate the writings by connecting them to Paul and his circle of co-workers. The location of the letters in time and space reflects the ongoing construction of a “landscape of memory” in the early church.”

Conrad Thorup Elmelund and Tommy Wasserman. “Second Timothy: When and Where? Text and Tradition in the Subscriptions” (pp. 202–26).
“Based on full collations of the subscriptions to 2 Timothy in 485 Greek manuscripts, this study presents the textual tradition and development of these subscriptions and explains their relationship to other subscriptions, paratexts, the internal evidence in 1–2 Timothy, Acts, and the wider church history. The study tracks the source(s) be-hind the tradition that the letter was sent to Timothy, installed as the first bishop of the church of the Ephesians, sent from Rome when Paul had appeared before Nero a second time and relates this tradition to the competing ancient biographies of Paul.”

Chris S. Stevens, “Titus in P32 and Early Majuscules: Textual Reliability and Scribal Design” (pp. 267-87)
“Manuscripts in the ancient world are the products of many scribal decisions. The relationship between the final product of these scribal choices and the functionality of the text, both textual and paratextual, is easily underestimated or ignored. To move forward, this chapter conducts a process of manuscript criticism of P32. First, the textual transmission will be compared with other manuscripts for transmissional lines. Second, the paratextual features, most notably segmentation and layout, are assessed and compared across the first millennium. The results indicate the scribal transmission was highly uniform, P32 is from a multi-text codex, and the design fea-tures in Codex Sinaiticus strongly suggest a Sitz em Leben within public reading and liturgical services.”
