Facet browse. Explore 16,000+ entries through a new Facet browser. Browse uses eight facets—dimensions such as era, geography, specialty, technology, institutions, reference, science, and social/historical studies—each grouping many clickable tags (e.g. Medieval, United States, Surgery). Select one tag per facet; choices combine across facets with live counts. A subject searchbar maps familiar Garrison Morton subject headings to their tags. Facets supplement the subject tree for exploratory browsing.  Indexing of entries to subjects remains unchanged.

Reorganized subject tree. The subject browser’s top level was reduced from 285 root headings to twelve broad categories (History & Social Studies, Reference, Clinical Specialties, etc). All prior leaf subjects with entries still exist—only navigation changed.

A Revised / Classic toggle on the Subjects tab lets you switch between the new grouped layout and the original flatter top-level organization (~285 headings). 

Subject hierarchy and facet mapping remain a work in progress—feedback welcome.

Maps. Results can show publication places and places mentioned in annotations on a new, interactive map.

Author portraits. Thousands of public-domain author images appear across the site.
