How would the service work with Collection Search Center? SIRIS? - Make recommendations for what and how to implement."

"In this paper we propose a multi-agent Selective Dissemination of Information service to improve the research community's access to digital library resources. The service also provides a new recommendation approach to satisfy researchers' specific information requirements." "Semantic Web technologies and fuzzy linguistic modelling provide the means to develop value-added services for digital libraries, which improve users' access to resources of interest to them. Furthermore, the recommendation approach here proposed allows researchers to satisfy specific information needs not covered by traditional recommender systems."

"Web Single Sign-On Metadata Exchange Protocol is a Web Services and Federated identity specification, published by Microsoft and Sun Microsystems that defines mechanisms for a service to query an identity provider for metadata concerning the protocol suites it supports. The goal of this operation is to increase the ability of a given service to interoperate with a given identity provider.1"

"MasterKey is a growing and evolving family of tools for building sophisticated information discovery solutions. They can be used individually, or they can be combined together using a shared service-based architecture. Some of the tools have been released by Index Data under OSS (open source software) licenses, whereas others, at this time, are made available exclusively to our customers. To complement the software, Index Data offers a full range of support, consulting, and development services. For businesses, our components are flexible and modular enough to fit into practically any existing software platform. For consortia and larger libraries, we offer an opportunity to create a solution which is uniquely adapted to local needs, while also based on open software components and open standards."

"Discovery services have begun to spring up. This article is my attempt to catalog and characterize them. Consider this article to be an introduction that sets the stage for future analysis articles."

"WorldCat Local is the single search that connects people to all your library materials-physical, electronic and digital-as well as to the delivery services that get them what they need. It displays multiple types of library resources, formats and locations in a single relevancy-ranked results set, provides high-level Web visibility for your library, interoperates with existing locally-maintained circulation and delivery services, connects seamlessly to everything in your collection and simplifies the discovery-and-delivery experience for your library users."

This article will explore the space between Summon's out-of-the-box user interface and full developer API, providing practical advice on tweaking configuration information and catalog exports to take full advantage of Summon's indexing and faceting features. The article then describes the creation of OSUL's home-grown open source availability service which replaced and enhanced the availability information that Summon would normally pull directly from the catalog.

"SRU (Search/Retrieve via URL) et SRW (Search/Retrieve Web service) sont deux protocoles qui, succédant à Z3950, en constituent une évolution, et ce vers les technologies web, via les webservices. Maintenus par la Bibliothèque du Congrès, et destinés à faciliter la recherche sur Internet, ils se fondent sur le langage CQL (Common Query Language, standard de syntaxe de requête), qui présente l'avantage d'une (relative) lisibilité. SRU/SRW spécifient tout à la fois la syntaxe des requêtes, et celle des réponses données à ces requêtes. SRU/SRW permettent d'interroger simplement, via le protocole http du web, des bases de données jusqu'alors cachées ou plus difficilement accessibles. La version 1.1 de SRU a été publiée en février 2004, et devrait être suivie d'une version 1.2 actuellement en cours de développement. "

"Metasearch, parallel search, federated search, broadcast search, cross-database search, search portal are a familiar part of the information community's vocabulary. They speak to the need for search and retrieval to span multiple databases, sources, platforms, protocols, and vendors at one time. Metasearch services rely on a variety of approaches to search and retrieval including open standards (such as NISO's Z39.50), proprietary API's, and screen scraping. However, the absence of widely supported standards, best practices, and tools makes the metasearch environment less efficient for the system provider, the content provider, and ultimately the end-user.

"Traditional on-line search services such as Dialog, DataStar and Lexis provide a wide range of search features (boolean and proximity operators, truncation, etc). This paper discusses the use of these features for effective searching, and argues that these features are required, regardless of advances in search engine technology. The literature on on-line searching is reviewed, identifying features that searchers find desirable for effective searching. A selective survey of current digital libraries available on the Web was undertaken, identifying which search features are present. The survey indicates that current digital libraries do not implement a wide range of search features. For instance: under half of the examples included controlled vocabulary, under half had proximity searching, only one enabled browsing of term indexes, and none of the digital libraries enable searchers to refine an initial search. Suggestions are made for enhancing the search effectiveness of digital libraries; for instance, by providing a full range of search operators, enabling browsing of search terms, enhancement of records with controlled vocabulary, enabling the refining of initial searches, etc."

a compilation of chapters by 25 librarians around the world who have used mashups within their organisations to improve services to their patrons. Each chapter includes first-hand experiences and tips for using outside data sources to enhance library offerings.

The following tools can be used to connect to Ryerson Library resources and services from other sites on the web : - Google and NetVibes Search Gadget - Ryerson Library Lookup from Amazon/Indigo/Google Books - Search the Ryerson Library Catalogue from Facebook - Get It Buttons in Google Scholar - Ryerson Library Catalogue Search

"Many Web 2.0 services (including Library 2.0 catalogs) make use of folksonomies. The purpose of this paper is to cut off all tags in the long tail of a document-specific tag distribution. The remaining tags at the beginning of a tag distribution are considered power tags and form a new, additional search option in information retrieval systems. In a theoretical approach the paper discusses document-specific tag distributions (power law and inverse-logistic shape), the development of such distributions (Yule-Simon process and shuffling theory) and introduces search tags (besides the well-known index tags) as a possibility for generating tag distributions."

"Library data has been designed to be read and interpreted by librarians and users. Although there are some controlled data fields, most of what is in the library catalog entry is text. The machine as user has not gotten a great deal of attention in the library cataloging environment. Now there's yet another potential user of library data, and that user is the Web and services that function on the Web. (...) This issue of Library Technology Reports provides an explanation, using concrete models and real-world examples, of how to facilitate this transformation."

"In 2007-2008, the DLF convened a Task Group to recommend standard interfaces for integrating the data and services of the Integrated Library System (ILS) with new applications supporting user discovery. This page gives access to the group's recommendation, related materials, and information on followup activities."

"Catalogue 2.0? Catalogue de nouvelle génération? Peu importent les appellations, finalement. Ce qui compte réellement, c'est la manière de gérer la transition, avec une attention particulière aux contenus et aux services, bref à la médiation. Ci-dessous, une sélection de ressources, de références, amorces possibles pour une discussion "globale", au sein de notre institution, sur les nombreuses questions: On y passe? Oui? Non? Pourquoi? Comment? Suivant quelles modalités? Avec quels outils, quelles fonctionnalités? Si vous le souhaitez, je vous invite à participer au débat en utilisant les commentaires pour alimenter la liste…"

"Ce protocole d'échange permet de créer, d'alimenter et de tenir à jour, par des procédures automatisées, des réservoirs d'enregistrements qui signalent, décrivent et rendent accessibles des documents, sans les dupliquer ni modifier leur localisation d'origine. Grâce au protocole OAI, une bibliothèque agissant en tant que fournisseur de données a la possibilité d'offrir une visibilité accrue à ses documents, notamment à ses publications électroniques ou à ses fonds spécialisés. Réciproquement, en tant que fournisseur de service, une bibliothèque peut réaliser une base de données ou un portail documentaire dans son domaine de spécialité ou sur un thème quelconque, en collectant les données descriptives de ressources et documents de tous types, accessibles sur l'Internet dans des entrepôts OAI."

"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."

"But commercial vendors, smelling a new market, are stepping in. Serials Solutions, a subsidiary of ProQuest, released a software product in July called Summon. The company has been negotiating deals with publishers and content providers to create a searchable index of their content. It's like Google, except what Summon provides is an index of the "deep Web" of paid content. So now university libraries that pay for a subscription to Summon can let their users search their licensed content as well as locally owned stuff, together. Summon has 17 customers so far, including Arizona State University and Dartmouth College. The catch? It can be expensive. Andrew S. Nagy, senior discovery-services engineer at Serials Solutions, wouldn't say how expensive. But the cost of a subscription can run into the tens of thousands, said one university administrator who was not authorized to discuss price and thus wanted to remain anonymous. Summon also does not have permission to display the full text of articles."
