Tech History
Preliminary work: MOBOT’s Botanicus http://www.botanicus.org
Funded by Keck Foundation & IMLS Working demonstration of how
nomenclators/databases (like Tropicos) can link into digitized scientific literature
Codebase reused for BHL, then changed to fit requirements for EOL

Name finding statistics
30 million pages scanned 70 million name strings found 60 million names verified with a
NameBankID
1.5 million unique names with a NameBankID
3.5 million unique names *without* a NameBankID This is where the interesting data live!!!

Services & APIs• OpenURL
– Facilitate links to citations: protologues, articles, references• Documentation:
http://www.biodiversitylibrary.org/openurlhelp.aspx– Useful to Nomenclators, Reference Systems
• IPNI• Tropicos
• Names Service– Return all occurrences of a name throughout BHL digitized
corpus• Documentation: http://bit.ly/2e6sg9
– Working out a strategy for obscure species– Algorithm improvements to detect nomenclatural &
taxonomic acts• New API

But where are the articles??
BHL scans cover to cover for monographs & serials
Have tested automated markup and article boundary extraction techniques Variety of typefaces & printing techniques
make a wholly automated solution close to impossible
So, when in need, crowdsource…

Opportunities
New technologies BHL-Europe: Scan List
New use cases & user communities BHL-Europe: Cultural history
New initiatives Data mining, markup, text correction
Redundancy, localization CONTENT!!
Biodiversity Heritage Library: http://biodiversitylibrary.org
BHL is…
A unique software tool Built to serve taxonomists’ & other
scientists’ research Enhanced by 250+ years of accumulated
knowledge Complementary to physical libraries
A shared, global resource An unparalleled opportunity for
collaboration
