Five vols. The four editions of price guides for modern first editions - Collecting Modern First Editions (vol.1) and Modern First Editions - Their Value to Collectors (vols.2-4) - and Children's Modern First Editions - Their Value to Collectors; the author's popular price guides which attempt to unite value and price into a harmonious, comprehensible relationship: an algorithm without an internet; illustrations of dustwrappers, anglocentric selection of authors, sometimes only particular titles, and brief summaries of authors' literary worth. Collecting Modern First Editions has laid in an autograph letter, signed from Joseph Connolly to a book collector responding politely to suggestions for authors to be included in future editions.
