Why we needed Ümlaut Georgia Tech motivations Needed data for Communicat Couldn't resolve conference proceedings Preprints, Postprints, Working Papers Tired of "clicking and praying" Johns Hopkins motivations Print holdings directly on page Catalog MARC 856 URLs Document delivery requests Loosely coupled interface flexibility --->>> Umlaut as platform

Interesting Engineering Just a mention... Local configuration Background services
Fütüre Feature wishlist Cover images (and more?) from Open Library Rochester “Getting Users Fulltext” page-skipping clone Google Books search? link to OCLC Identities xISBN/thingISBN use? Enhanced serial metadata Public access journal articles "Cited by" service Enhance metadata for citation manager export. Integrate local document delivery services Connectors for other knowledge bases
Fütüre U3 -- document-oriented database as store instead of rdbms Performance improvements Relying on web services is inherently latent Caching? Precoordinating more data? User-centric collection
