This volume investigates the identities, operational timelines, and professional locations of the individuals involved in the book trade across England, Scotland, and Ireland during the mid-seventeenth century. Henry R. Plomer, a noted bibliographer and historian of the printing trade, compiles extensive archival data to document the mechanics of the book industry during a period of significant political and social upheaval. The work provides a structured framework for understanding the distribution of knowledge and the commercial realities faced by printers and booksellers between 1641 and 1667.

Experts recognize this work as a foundational reference for scholars of seventeenth-century printing history and bibliography. Readers frequently note the dense, academic nature of the entries, which serve as a primary resource for historical research rather than casual reading.
