What is BHL? The Biodiversity Heritage Library is a consortium of natural history and botanical libraries that cooperate to digitize and make accessible the legacy literature of biodiversity held in their collections and to make that literature available for open access and responsible use as a part of a global “biodiversity commons.” The Biodiversity Heritage Library is a consortium of natural history and botanical libraries that cooperate to digitize and make accessible the legacy literature of biodiversity held in their collections and to make that literature available for open access and responsible use as a part of a global “biodiversity commons.”
Dear Sir / Madam Can i just congratulate you on an absolutely brilliant online resource. I am compiling a report on an invasive hydromedusae and could not believe the ease and efficiency of this web page which genuinely saved me weeks of my life Research that previously took months now takes only a few hours La plus grande #bibliotheque #botanique & #zoologique online The largest online botanical & zoological #library #BHL The freeing of knowledge may lead to new discoveries and changes in the way the natural world is perceived

Where are we? Scientific Name Extraction – Improved algorithm (Thanks uBio!) Articles – Extended BHL data model to store article metadata – Content and Process to harvest data from BioStor in place Create user interfaces for adding article metadata and associated files – Functional requirements defined – Process flow for adding article metadata and associated files – Implement UI changes Change BHL UI to accommodate article search Change BHL UI to accommodate article display (TOC)
Scientific Name Extraction TaxonFinder algorithm in production since 2008 – More than 100 million candidate name strings – More than 1.5 million unique, verified names – Available through UI, APIs, Data Exports & Internet Archive New collaboration with Global Names – Improved algorithm, better precision & recall – More data with TaxonFinder and Neti Neti!
Part-level metadata Disambiguating and locating structural components in the corpus Done by automated and crowdsourced means – Thanks Rod Page! Welcome others! Greatly increases semantic value of the dataset Addressing important – makes data addressable and thus linkable

Expanding scope Manuscripts, field notebooks –mostly handwritten, often with drawings Global expansion means dealing with non- Western script systems and a whole new set of OCR problems – Arabic materials from Bibliotheca Alexandria in Egypt
Transcribe Bentham A collaboration of the University of London Computer Centre, UCL Library Services and UCL Learning and Media Services with consultation from the UCL Centre for Digital Humanities Volunteer users can log-in and transcribe previously unstudied and unpublished manuscripts from the Bentham Papers collection in UCL Library's Special Collections in the Transcription Desk.UCL Library's Special Collections Transcription Desk Since launch, volunteers from around the world have transcribed several thousand Bentham manuscripts to an extremely high standard. Results and findings: http://www.digitalhumanities.org/dhq/vol/6/2/000125/000125.html http://www.digitalhumanities.org/dhq/vol/6/2/000125/000125.html

Purposeful Gaming DIGITALKOOT Joint project run by the National Library of Finland and Microtask to index the library's enormous archives so that they are searchable on the Internet for easier access to the Finnish cultural heritage.National Library of FinlandMicrotask Launched on Feb 8 2011, nearly 110 000 participants completed over 8 million word fixing tasks by Nov 29 2012 DigiTalkoot enabled volunteers to participate in this fixing work by playing games.
