While a reconstruction of the whole of William James's personal library isn't feasible, there are significant portions of it that reside within the Harvard University Library system and this book is a partial reconstruction of their story. Reconstructing the Personal Library of William James offers a new, comprehensive account of the James collection at Harvard University, bringing together all known Harvard-owned entries into one comprehensive volume. The annotated bibliography contains data on 2,554 entries (2,862 volumes) from James's personal library, including both the 1923 Philosophical Library and all known additional donations by James and his family. . Each entry, when applicable, contains the following data points: Harvard Library location and call number, provenance, bookplate, accession record, autographs, inscriptions, ownership marks, indexical annotations, markings, and marginalia. To orient the reader, Ermine L. Algaier IV supplements the bibliography with essays that examine the history of the James's library at Harvard, assess the size of the collection and how it came to reside at Harvard, and showcase patterns that emerge from looking at the collection as a whole. Additional essays are devoted to explaining the source lists and archival resources used in reconstructing James's personal library, as well as outlining steps for continued research on the collection.
