"Randomly selected undergraduates at Brigham Young University, Brigham Young University-Idaho, and Brigham Young University-Hawaii, all private universities sponsored by The Church of Jesus Christ of Latter-day Saints, participated in a study that investigated four questions regarding federated searching: (1) Does it save time? (2) Do undergraduates prefer it? (3) Are undergraduates satisfied with the results they get from it? (4) Does it yield higher-quality results than nonfederated searching? Federated searching was, on average, 11 percent faster than nonfederated searching. Undergraduates rated their satisfaction with the citations gathered by federated searching 17 percent higher than their satisfaction using nonfederated search methods. A majority of undergraduates, 70 percent, preferred federated searching to the alternative. This study could not ultimately determine which of the two search methods yielded higher citation quality. The study does shed light on assumptions about federated searching and will interest librarians in different types of academic institutions, given the diversity of the three institutions studied."

"(...) We list here some of the search and retrieval, content and other features that might be expected from a resource discovery system and which of the four systems (WCL, Encore, Summon, LibraryFind™) provide that functionality."

"Les interfaces graphiques de recherche relèvent presque toutes d'un modèle unique et primaire : un champ de saisie uniligne et un bouton permettant de valider la requête saisie dans le champ. Face à la diversité des individus et de leurs besoins en informations, de nombreuses techniques de visualisation et d'interaction innovantes ont émergés ces dix dernières années. Pourtant ces innovations sont rarement utilisées et le but de cet article est de faire le point sur l'état de l'art des techniques de visualisation et d'interaction qui peuvent être pertinentes pour la recherche d'information."

"An API for effective interoperation between integrated library systems and external discovery applications"

"The University of Calgary's Libraries and Cultural Resources became a beta partner with Serials Solutions' unified discovery service, Summon, in the spring of 2009. Since then it has worked to include metadata from numerous disparate systems in a single index to drive discovery in a Google-like environment. The University of Calgary has examined how MARC and other metadata schemas are mapped into Summon with an eye to ensuring the maximum possible population of index fields representing facets in addition to adhering to the established standards for cross mapping metadata schemas and indexing. The University of Calgary has investigated existing standards and worked closely with the Summon team to create mappings that reflect how MARC and other metadata can ultimately be used in big indexes. Combined with the normalization or collapsing of metadata records representing the same resource into a single metadata-rich record, fully leveraging MARC and other metadata in big indexes should not only level the metadata playing field but make competition between records a non-issue."

"Koha utilise le moteur d'indexation open-source Zebra. Le site http://www.indexdata.dk/zebra/ présente Zébra comme : "un outil hautement performant permettant d'indexer et de rechercher du texte structuré. Il est capable de lire les enregistrements dans différents formats d'entrée (par exemple email, XML, MARC) et donne accès aux données grâce à l'utilisation d'équations de recherches booléennes et de requêtes en texte libre. Zebra supporte de grosses bases de données ( dizaines de millions d'enregistrements, dizaines de gigabytes). Il permet la mise à jour incrémentale de la base de données sur des systèmes en production. Du fait que Zebra support le protocole de recherche Z39.50, vous pouvez rechercher dans les bases de données Zebra par l'intermédiaire d'une grande variété de programmes et outils, commerciaux ou libres, qui sont capables de communiquer via ce protocole."
