Implementing “Find Articles”: A low-altitude view of metasearching
Implementation decision points 1 Positioning the metasearch service to promote its use Configuring the interface and retrieval-set limits to optimize performance Establishing Z39.50 connections to enable similar searches Configuring the search-results screen to normalize heterogeneous data
Implementation decision points 2 Parsing A&I-vendor metadata to maximize OpenURL connections Interpreting user transactions to improve performance
History of CUL gateways Mann Library Gateway (1991) Cornell University Library Gateway (1998) E-Reference Collection (2001) Find Articles/Find Databases/Find e-Journals (2003- )
Service enhancements Existing functions Go to database from search results Browse by subject Navigate to other CUL resources Authenticate users for restricted resources
We tried to put metasearching in a single interface with existing database-metadata search and browse functions
We settled on a 3-tab, 3-service structure
“Find Articles” became the metasearch service
Z39.50 connection parameters “Keyword” use attributes varied: 1016 (OCLC, ProQuest, RLG, WebSPIRS); 1017 (RLG); 1035 (EBSCO, Wilson); 4 (EBO—title only) Structure attributes were tricky: phrase (Wilson); unspecified (EBSCO, PQ); word list (EBO, OCLC, RLG, WebSPIRS)
We normalized heterogeneous search results
