Points we’ll cover Development Methodology Usage Stats APIs Data Mining External Connections iTunes U DOIs & Mendeley Data Challenges & Gaming @chrisfreeland
Methodology: Evolutionary Prototyping • Find a problem, code a solution, test evaluate with staff users, push it out to production • Example: Fuzzy Searches for bibliographic metadata • Proceedings Philadelphia • Darwin 1859 • Proc Soc Zool Lond Moved into production yesterday http://blog.biodiversitylibrary.org/2012/04/new-improved-bhl-search-interface.html
iTunes U • Since Launch on Feb 2: • 50,120 browses • 1,646 subscriptions • 6,007 downloads @chrisfreeland
DOIs Have assigned 49,000 DOIs to BHL monographs @chrisfreeland
Purpose of exercise • Make legacy scientiﬁc literature citable via modern systems • Make 250+ years of scholarly communications available via new tools • Assign contemporary identiﬁers to legacy literature • DOI • ISBN • ISSN @chrisfreeland
DOI, ISBN, ISSN, ei, ei,…uh oh… • Ran into trouble with each agency • BHL isn’t a publisher • BHL is a consortium, not a separate legal entity • BHL doesn’t own all the content it serves • “We know we need a policy on that…” …and on…and on…for more than 3 years… @chrisfreeland
Challenge: Title Matching for Uniqueness • Only want 1 DOI per intellectual, citable unit • Differences between cataloging publishing • Libraries: dataﬁeld tag=245 ind1=1 ind2=4 subﬁeld code=aThe amoebae living in man;/subﬁeld subﬁeld code=ba zoological monograph,/subﬁeld subﬁeld code=cby Clifford Dobell./subﬁeld /dataﬁeld • Publishers: titleThe amoebae living in man; a zoological monograph/title @chrisfreeland
Challenge: Monographs/Series/Monographic Series • “Report on the Rhynchota collected by the Wollaston Expedition in Dutch New Guinea” • Published in 1914 • Bound catalogued as a monograph • Scanned as a monograph • Assigned a DOI as a monograph in BHL:http://dx.doi.org/10.5962/bhl.title.13791 • Transactions of the Zoological Society of London, vol. 20, pt. 11. • Presented by current publisher of that title as an article • Assigned a DOI as a journal article: http://dx.doi.org/10.1111/j.1469-7998.1912.tb07839x Guess who provides free access?
Challenge: Ownership of Backﬁles • Who owns public domain works? • Some publishers consider they have ownership of backﬁles for journals they currently publish • Long running series in natural history • Curtis’s Botanical Magazine, since 1787 • Those publishers assign DOIs to their current volumes • BHL assigns DOIs to the public domain works we’ve digitized Guess who is upset?
