The BHL is…• A consortium of 13 natural history,
botanical libraries and research institutions
• An open access digital library for legacy biodiversity literature.
• An open data repository of taxonomic names and bibliographic information
• An increasingly global effort
BHLLITA 2011
Problem: Books vs. ArticlesLibrarians manage books Users need articles
BHLLITA 2011
Solution: “Article-ization”Creating articles manually, through the
help of our users: BHL PDF Generator
Creating articles through automated means: BioStor http://biostor.org/issn/0006-324X

What is an “article” anyway?

Questions for Data Analysis• What is the quality, or accuracy, of
user provided metadata?• What kinds of content are users
creating?• How can we improve the PDF
generator interface?
BHLLITA 2011
Stats• Jan 2010-Apr 2011
– Approx 60,000 pdfs created from PDF Generator
– 40% of those (approx 24,000) were ingested into CiteBank (PDFs without user-contributed metadata excluded)
• 5 reviewers analyzed 945 pdfs (approx 3.9% of the 24,000+ articles going into Citebank)
**Thanks to reviewers Gilbert Borrego, Grace Costantino, and Sue Graves from the Smithsonian Institution
BHLLITA 2011
Methodological approach
• Quantitative – numerical rating system
• Rated titles, authors, beg/end pages• Its “findability” within CiteBank
search often determined how it was rated
BHLLITA 2011
Ratings SystemTitle
• 1=has all characters in title letter for letter• 2=does not have all characters in title letter for
letter but still findable in CiteBank search • 3= does not have all characters in title letter for
letter and is NOT findable via the CiteBank search
LITA 2011 BHL
Ratings SystemAuthor
• 1=has all characters in author(s) last name letter for letter
• 2=has at least one author’s last name spelled correctly
• 3=has no authors or none of the author’s last names are spelled correctly
LITA 2011 BHL
Ratings SystemArticle beginning & ending pages
• 1=has all text pages for an article, from start to end
• 2=subset of pages from a larger article • 3=a set of pages where the intellectual content
has been compromised.

What did we learn?• Ratings were better than we
expected• Many users took the time to create
decent metadata • “good enough” is not great but is still
“findable”

BHL-Australia’s new portalhttp://bhl.ala.org.au/
there’s always room for improvement
Other factors
But of course…..
BHLLITA 2011
Changes we madefor UI so far
• Asking users if they want to contribute their article to CiteBank
• Making article title a required field and validating it so its at least 2 or more characters
• Review button for users to review page selections and metadata (inspired by BHL-AUS)
• Reduced text and increased more intuitive graphics (inspired by BHL-AUS)
BHLLITA 2011
Brief survey of proposed changes
• Overwhelmingly positive response to proposed change
there’s always room for improvementBut of course…..
BHLLITA 2011
Success Factors• Monitor the creation of the metadata
to look at user behavior and patterns
• Engage with your users
• Incentivize your users
