xrefer, an online ready reference service that provides full-text, aggregated content to academic, public, and corporate libraries, has released version 2.0 of its xreferplus service, which includes improved information visualization capabilities (a new "Research Mapper"), a host of new content, and unit conversions.
The Research Mapper is a visual map that displays how search terms and topics in xreferplus are interconnected. Users can access the Mapper from any set of search results, enabling them to quickly explore the links among topics within the area they're researching. The Research Mapper displays all of the xreference links that are included in a set of search results in an interactive format that illustrates how--and how closely--the search results are connected to other xreferplus entries. Research Maps can guide users to the most relevant information related to their research, and can lead users to areas that warrant further exploration. A public version of the Mapper is available at www.xrefer.com/research.
Recent additions to xreferplus include The Bridgeman Art Library Archive, Webster's New World Computer Dictionary, Dorland's Illustrated Medical Dictionary, and The Academic Press Dictionary of Science and Technology. The company continues to add new titles regularly, focusing on content that includes image and audio files in addition to full text entries.
xrefer has also added Unit Conversions to its reference library, which will enable users to compare and calculate measurements of area, distance, energy, speed, volume, weight. and more. The conversion calculator simultaneously displays all units of measure within a given category, and is integrated with xreferplus.
