The essays are illustrated, with references to catalogue numbers printed in the margins. Appendices include exhibition histories, relevant correspondence, a list of portraits of Nasmyth (unillustrated), a family tree, and documents. The catalogue also includes information from unpublished documentation from the archives at St. Andrews University Library. The second part contains a list of titles and catalogue numbers. The author notes that some works of questionable attribution were excluded. The catalogue is followed by a bibilography, including notes on Nasmyth's descendants.
