A custom search engine to explore biodiversity literature alongside biomedical literature (e.g., PMC, MEDLINE). The service provides access to Pazi’s taxonomic treatments in JATS/TaxPub formats. Based on the SIB Literature Services (SIBiLS), all contents have been semantically enriched with several domain-specific onto-terminologies (e.g. NCBI Taxonomy, Open Tree of Life, Gene Ontology) to enable users to author semantically enhanced queries. Inspired by the “One Health” recommendations of WHO, the service is enhancing the coverage of PubMed Central by integrating a growing collection of open-access full-text publications in biodiversity-related fields, such as ecology and taxonomy. The data are distributed under CC-BY licenses in BioC formats.
