Making data work hard

The user experience: from search to rich browse Capturing user contribution

Data mining


Context: value

Amazoogle: we can add significant value. We should be looking for organizational frameworks within which we can do this.

ROI: libraries invest in data but do not extract as much value as they might from it. Unless we release more value, then the argument for this investment becomes weaker. The user experience Management intelligence

WIKI in WorldCat

Capture user input in structured ways


Extending Wiki’s utility

Wiki: supported markup:

wikitext page editing:

a single text block

searches: full text searching

collections managed: one per wiki

MetaWiki: supported markup:

wikitext structured data (e.g., MARC,

METS, DC…) page editing:

a single text block, or, field level

searches: full text searching fielded searching

collections managed: one/multiple per MetaWiki

Built on top of standards (OAI, OpenURL, SRU)


Management intelligence: data mining

Data Bibliographic data Transaction logs …

Need to mine this data for intelligence that creates value for libraries and users

OCLC Research undertaking a number of data-mining projects aimed at: Knowing more about the characteristics of library collections Creating interesting and useful data displays Generating intelligence to support library decision-making


Know Your Audience!

Implies: we can infer materials’ audience level from holdings patterns, which in turn can support:• Collection management• Readers’ advisory services• Reference services• Information retrieval

Holdings represent selection decisions by librarians … implies there are about 1 billion individual selection decisions in the WorldCat holdings file

Selections are made to serve the interests of a library’s target community …• Associate target community (audience level) to particular library profiles - e.g., ARL, non-ARL academic, public, K-12 school …

Paper forthcoming!

The Implications of Google Libraries …

Potentially covers about one third of print books in WorldCat

~60 percent of total G5 books held by only one of the Google 5

Less than 5 percent held by all of the Google 5

~20 percent of total G5 print books out of copyright

Paper forthcoming …


“Last Copy”: Identifying At-Risk Materials

~23 million WorldCat records have only a single holding attached

Libraries need to know what portions of their collections are:Rare … Rare and valuable …“Last copy” (artifact and/or content)

Identification of rare materials essential intelligence in support of storage, digitization, and preservation decision-making

Data-mining study of Vanderbilt holdings in WorldCat:• Identified 23,000 items held uniquely by Vanderbilt

• ~60 % are print books• ~60 % produced prior to 1950; ~25 % produced after 1970

Paper forthcoming!


Looking at Library Print Book Collections … Systematically

32 million print books, representing26 million distinct works

Half of print books published after1977; more than 80% still “in copyright”

Rareness is common! Only a third of print books have more than five holdings; half have two or less

OCLC/Ithaka collaboration: Use WorldCat to characterize the “system-wide” print book collection – i.e., aggregate print book holdings in WorldCat

Intelligence of this kind can help establish digitization prioritiesand inform preservation planning

Only about 120,000 works had bothprint book and e-book manifestations
