This volume serves as a comprehensive reference tool designed to identify the true authorship of works published anonymously or under pseudonyms within the English literary canon. The authors, including Samuel Halkett and John Laing, utilize extensive archival research and historical records to attribute obscure or hidden texts to their original creators. This work functions as a critical supplement to the broader multi-volume project, providing updated entries and corrections to previous bibliographic data.

Scholars and librarians frequently cite this series as a foundational resource for bibliographic verification and literary research. Experts note the high level of academic rigor required to compile such exhaustive attribution data, making it a standard reference in university libraries.
