We reproduce by permission the 1967 checklist created by Hiroshi Mizuta of the titles that were owned by Adam Smith. This checklist is supplemented by a list of additional once-elusive titles. The checklist plus the supplement, provided together here, comprise a handy means for determining whether a title was in Smith’s personal library: Scholars may search the PDF file for words in the title or author’s name, and should try words individually, or only a distinctive part of a word, for best results. If a title is not contained herein, then one should feel quite sure that if Smith did ever own a copy the work, no one of this realm does or ever shall know that to have been the case.
