An indispensable map to chemical literature from 1492 to 1897. A vital guide for scholars. Henry Carrington Bolton's A Select Bibliography of Chemistry, 1492-1897 (First Supplement) gathers references across early modern chemistry and nineteenth century science, offering a compact yet authoritative chemistry bibliography collection for researchers, librarians and collectors. More than an index, this scientific book supplement serves as a clear chemical literature guide and historical chemistry reference: it directs readers to primary texts, situates important works in their intellectual context and flags editions prized by collectors of rare science books. Written with archival care and scholarly clarity, the supplement supports academic researchers and curious readers drawn to the roots of modern chemical thought. It sits alongside other science bibliographies as both a specialised tool and a luminous roadmap for the history of chemistry. Meticulously compiled during a decisive span of scientific change, Bolton's supplement has enduring value for library collection development and for historians assembling science bibliographies. It functions as a practical academic researchers resource for citation tracing, provenance work and historical research, and as a map for chemistry historians exploring the transition from alchemy to systematic experimental chemistry. Librarians and curators use it when assessing acquisitions for nineteenth century science holdings; collectors use it to identify editions and variant printings. For casual readers, the volume opens an accessible doorway into the evolution of chemical ideas; for classic-literature collectors, it supplies the bibliographic scaffolding that turns curiosity into a coherent collection. Beyond immediate reference, the supplement enriches interpretation: curators curating exhibitions, teachers designing modules on the history of chemistry, and independent scholars conducting provenance or reception studies all return to Bolton for a reliable starting point. Even casual browsing yields surprising paths through the development of chemical thought. Republished by Alpha Editions in a careful modern edition, this volume preserves the spirit of the original while making it effortless to enjoy today - a heritage title prepared for readers and collectors alike.
