Challenges Finding Information

Information overload Millions of articles, books, and web sites Thousands of sources and search interfaces

Answers often require an interdisciplinary or multidisciplinary approach

Need high quality information quickly and easily

Multi-Resource Search Engines Help Reduce

the Number of Places You Need to Search

Examples of Major Sites: Web of Knowledge CSA Illumina EbscoHost OCLC Proquest

Examples of Specialized Sites: ChemID Plus DiscoveryGate Entrez Science.gov ScienceResearch.com SciFinder Scitopia ToxNet WorldWideScience

But You Often Need to Search Resources Provided by Different Providers

Federated searching lets you simultaneously search multiple sources from different providers using one query

Key features of a good federated search service include: Search > 10 resources simultaneously Sources searched in real time Search engine is fast and has excellent relevancy ranking of results Users can refine, analyze, sort results, and go to items from a specific

source Results are de-duplicated so that same item doesn’t appear multiple

times Easy access to the full-text for content licensed by Stanford Export citations to a reference manager Save queries or set up alerts Integrate searching into your local environment (e.g. CourseWork, web

pages).

xSearch Developed by Deep Web Technologies in consultation with

SULAIR, xSearch is a federated search service for current students, faculty, and staff at Stanford. The URL is:

http://xsearch.stanford.edu

Due to licensing restrictions, up to 100 items are retrieved for most sources.

Number of items retrieved from a resource varies each time a search is performed.

Most duplicate citations are eliminated before search results are displayed.

Unlike many web search engines, xSearch queries are performed in real time.

Note: ALL links open in the same window. Use Open New Tab/New Window feature in a browser to keep search results page when you want to view full records/full-text.

About the eBooks Category

13

The eBooks category does not include all ebooks at Stanford.

Some providers are not included in xSearch yet (e.g. Cambridge Books Online).

Other providers are in xSearch but because it is not possible to do an initial search on only ebooks, these providers were not added to the eBooks category in xSearch (e.g. Elsevier, Springer, Wiley) .

About the Multi-disciplinary Category

14

Resources in this category are a “short list” of popular resources that contain materials in more than one subject area.

Use this category for a quick exploratory search.

Multi-disciplinary resources are also included to subject-specific categories as appropriate.

Use a subject-specific category for a more in-depth search.

15

Custom Search Engines

Groups of resources for a Subject or a Course have been created by subject specialist librarians for your use.

Custom Search Engine Selections by Subject Area (as of 9/28/2011 )

Sample Search We want to find info about Green Energy in California.

To broaden search, we are including two synonyms for green - “alternative” and “sustainable.” We are searching sustain* to find words that begin with this stem.

We are limiting California to the Title field as doing so means that an author considered California to be important enough that it should be present in the title. And like Google Scholar, searching California as a keyword retrieves items that include California as a part of the author’s address.
