Next Gen Catalog Forum Where do we go from here?
Online catalog to facilitate successful search • Search to help a researcher find what she or he wants • Need to provide 1) broad net to find “all” that is out there, 2) narrow down to relevant resources, and 3) a way to do known item searching • Intuitive navigation between results • Need to allow the user to figure out the easiest way to get this content, whether full-text book, article, print resource, archive, dataset, image, etc.
Next Gen search can allow: • Integration of formats (and the accompanying metadata) • Better inclusion of table of contents (as part of MARC record or as separate element to search) • Relevancy ranking of terms, names and phrases within the index of book or the actual content of the full-text book • Interconnectivity of resources – moving from citation to citation (as more and more resources are in digital form)
More and more metadata at our fingertips • Digitization projects – Google, Microsoft, Open Content Alliance, Amazon, Million Book Project, EU digitization project, etc. • ONIX feeds from publishers and vendors • Using METS and ATOM to create file structure to pull these desperate data elements together • Using OAI-PMH or OAI-ORE to harvest data from various sources • OCLC’s work to provide comprehensive uber-metadata records for all resources, combining data from libraries and publishers to create
Facets • Material Type • Author/Creator • Date • Subject • Library Location • Language • Call Number • Availability • Series • Serial title changes • Translations • Works cited • Keyword clouds • Dewey has great potential as a facet
Facets can utilize MARC to its fullest capabilities • Fixed fields • Series statements (440, 490, and 830 fields) • Uniform titles (240) – linking translations • Language (041) • Identifiers (022, 035, 776) • Publisher • Author fields (1xx, 7xx • Authority records play an important in all this • Accuracy is so critical to this process
MARC can’t handle all data • Images • Value-added information such as biographies, reviews, automation of inclusion of TOCs • Indices • Bibliographies • Cross references within sources • Correction of past practices (not including all the authors, abbreviations, publication information, etc.)
