# bhl.literature.fulltext

Search within the digitized full text of Biodiversity Heritage Library publications for a specific term or phrase. Unlike the catalog search, full-text search scans the OCR-transcribed content of scanned pages, making it possible to find publications that mention a specific organism, location, concept, or measurement even when the keyword does not appear in title or subject metadata. Returns matching publications with title, authors, publisher, date, and direct BHL URLs. Use bhl.literature.search for faster metadata-only catalog queries.
