The BHL website was recently updated for new fields to download content. The TSV Data Exports are being updated to mirror this change. Please review these changes if you rely on the field order instead of the field names of the TSV file.
The Biodiversity Heritage Library is an open access digital library for biodiversity literature and archives. BHL’s global consortium of natural history, botanical, and research libraries cooperate to digitize and make their collections accessible as a part of a global “biodiversity commons.”
