The Ümlaut is an open source OpenURL middleware layer intended to improve the link resolving chain by analyzing incoming citations and intelligently querying resources to better enable access to them. The Ümlaut takes multiple approaches for locating items such as conference proceedings, preprints, postprints and gray literature utilizing search engines, Amazon, social citation managers and more. By utilizing the Worldcat registry, it is also personalizable and geospatially aware of available collections allowing access to all resources available to the user beyond the subscriptions of the Ümlaut's host institution. This talk will cover the history, architecture and community of this project.

Pubmed, Crossref
SFX
Local catalog, consortial catalog, Worldcat.org
in a variety of ways (xISBN, etc.)
Amazon (if ISBN)
Google API, Yahoo API
Social Bookmarkers: del.icio.us, Connotea, CiteULike, etc.

5. Why we needed Ümlaut
Georgia Tech motivations
Needed data for Communicat
Couldn't resolve conference proceedings
Preprints, Postprints, Working Papers
Tired of quot;clicking and prayingquot;
Johns Hopkins motivations
Print holdings directly on page
Catalog MARC 856 URLs
Document delivery requests
Loosely coupled interface flexibility
