ANN ARBOR, Mich. - OAIster Reaches 10 Million Records.

We live in an information-driven world-- one in which access to good
information defines success. OAIster's growth to 10 million records
takes us one step closer to that goal.

Developed at the University of Michigan's Library, OAIster is a
collection of digital scholarly resources. OAIster is also a service
that continually gathers these digital resources to remain complete
and fresh. As global digital repositories grow, so do OAIster's

Popular search engines don't have the holdings OAIster does. They
crawl web pages and index the words on those pages. It's an
outstanding technique for fast, broad information from public
websites. But scholarly information, the kind researchers use to
enrich their work, is generally hidden from these search engines.

OAIster retrieves these otherwise elusive resources by tapping
directly into the collections of a variety of institutions using
harvesting technology based on the Open Archives Initiative (OAI)
Protocol for Metadata Harvesting. These can be images, academic
papers, movies and audio files, technical reports, books, as well as
preprints (unpublished works that have not yet been peer reviewed).
By aggregating these resources, OAIster makes it possible to search
across all of them and return the results of a thorough investigation
of complete, up-to-date resources.

Ann Devenish, Publication Services Project Manager at Woods Hole
Oceanographic Institute, notes that "Harvesting by OAIster is a
primary 'selling point' when we talk to scientists and researchers
about the visibility, accessibility, and impact of their
contributions in an institutional repository. From their own
experiences they know that a search using one of the popular search
engines can bring back thousands (if not, millions) of results which
will require careful and time-consuming screening, with no guarantee
that they will ever get to the content they seek. A search of
OAIster, across hundreds of open and scholarly archives and millions
of records, brings back results with the key metadata elements that
allow for quick identification of, and easy navigation to, the
content they seek."

OAIster is good news for the digital archives that contribute
material to open-access repositories. "[OAIster has demonstrated
that]...OAI interoperability can scale. This is good news for the
technology, since the proliferation is bound to continue and even
accelerate," says Peter Suber, author of the SPARC Open Access
Newsletter. As open-access repositories proliferate, they will be
supported by a single, well-managed, comprehensive, and useful tool.

Scholars will find that searching in OAIster can provide better
results than searching in web search engines. Roy Tennant, User
Services Architect at the California Digital Library, offers an
example: "In OAIster I searched 'roma' and 'world war,' then sorted
by weighted relevance. The first hit nailed my topic-- the
persecution of the Roma in World War II. Trying 'roma world war'
in Google fails miserably because Google apparently searches 'Rome'
as well as 'Roma.' The ranking then makes anything about the Roma
people drop significantly, and there is nothing in the first few
screens of results that includes the word in the title, unlike the
OAIster hit."

OAIster currently harvests 730 repositories from 49 countries on 6
continents. In three years, it has more than quadrupled in size and
increased from 6.2 million to 10 million in the past year. OAIster
is a project of the University of Michigan Digital Library Production
