The document outlines various user needs and requirements for developing the Biodiversity Heritage Library (BHL) digital platform. It discusses needs such as searchable and browsable literature, digital page turning and multiple views of texts, translations, optical character recognition (OCR) of texts, machine-readable metadata standards, persistent identifiers for works, taxon-based bibliographies, multiple representations of works, a citation resolver, and improved OCR capabilities. The goal is to make the literature within the BHL collection fully accessible and usable for researchers.
