• 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

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…

CrossRef DOIs: path of least

@chrisfreeland

Challenge: Title Matching for Uniqueness

•  Only want 1 DOI per intellectual, citable unit

•  Differences between cataloging & publishing

•  Libraries:

•  Publishers:

<datafield tag="245" ind1="1" ind2="4"> <subfield code="a">The amoebae living in man;</subfield> <subfield code="b">a zoological monograph,</subfield> <subfield code="c">by Clifford Dobell.</subfield>

</datafield>

<title>The 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?
