kcenter_search

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.

"(...) 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."

"What's really hard about real-time search is figuring out the meaning and value of those fleeting bits of information. The challenge goes beyond filtering out spam, though that's an important part of it. People who search real-time data want the same quality, authority, and relevance that they expect when they perform traditional Web searches. Nobody wants to drink straight from a fire hose."

"Librarians, teachers and parents have told us how hard it is for students to understand web searching. Boolify makes it easier for students to understand their web search by illustrating the logic of their search, and by showing them how each change to their search instantly changes their results. It's simple, immediate and easy to use with your class or in your library. Search results are presented through Google's "Safe Search STRICT" technology. There are two important caveats: a) no filtering technology is 100% secure, as this blog posting astutely points out and 2) we are unable to control or modify the results that we provide, beyond the filtering settings available through Google."

"Data visualization has finally gone viral, says guest columnist UC Berkeley e-learning librarian Char Booth, and we have Twitter to thank"

"Next-generation library catalogs have been getting good press for some time now. While uptake of these search tools has increased over the last year, next-gen OPACs are by no means ubiquitous yet. While the market continues to evolve, the marketplace for these products has matured significantly, with a fairly wide range of products available, both commercial and open source."

"Many libraries are now designing and implementing their own tools to meet users' needs for search and data discovery. The aim of this study is to share the experiences of the HAM-TMC Library, one of the largest US medical libraries, in creating and implementing such a tool. Many libraries accept federated search and other technologies directly from their library management system vendors as the simplest way to proceed with implementing new technologies. The HAM-TMC Library recognized that its particular information environment required learning the "problem space" thoroughly before investigating available options. As a result, the new tool the Library is providing is much more likely to meet specific user information needs."

"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."

"This editorial aims to introduce a special issue of Library Hi Tech on "Virtual research environments: issues and opportunities for librarians". It defines the concept of the virtual research environment (VRE), describes its relationship both to the virtual learning environment and to Web 2.0, and proposes that librarians play a central role in VRE development and use.

"This paper aims to discuss whether there is difference between pragmatic and scholarly approaches to data gathering in libraries."
