The essay combines practical guidance on bibliographic description and cataloguing with a compiled list of works issued under the pseudonym a lady whose authorship the compiler could not ascertain. It outlines principles for describing books, including attention to printing style, punctuation, beginnings and endings, errata, and methods for identifying anonymous and pseudonymous writers. Preliminary remarks and a preface explain the compiler's aims, limits, and appeal for assistance, and the volume discusses the challenges of recording nineteenth‑century English publications accurately. The book concludes with advertisements, an index, and notes on cataloguing practice meant to help readers supply correct bibliographic information.
