"This case study examines the use of Wikipedia by the Ball State
University Libraries as an opportunity to raise the visibility of
digitized historic sheet music assets made available in the university's
Digital Media Repository. By adding links to specific items in this
collection to relevant, existing Wikipedia articles, Ball State
successfully and efficiently expanded the user base of this collection
in the Digital Media Repository by vastly enhancing the discoverability
of the collection's assets...
"The results of this study show that the addition of links from relevant
Wikipedia articles to individual digitized assets in the Hague Sheet
Music Collection in the Ball State University Digital Media Repository
was an overwhelming success. Despite the fact that only 57 links to 40
assets were added to Wikipedia articles, pageviews for the collection of
149 assets roughly tripled as a result of this effort. The adding of
links at the item level provided a plethora of highly-visible entry
points to this collection's assets, raising awareness of the existence
of these resources to interested Internet users who were previously
unaware of these materials, as is suggested by the collection's use
statistics. The success of this initiative is also remarkable in its
efficiency, generating a large number of new digital patrons while
requiring relatively little time to plan and execute."
Includes an encouraging graph. :-)
