About the Web Information Service

Our Web Information Service provides simple, one-step searching across all our database collections, including: well as several additional resources, including:

Three Search Options

General searches conducted using the Web Information Service search box (on the Web Information Service home page) search across all the databases in the service. This method provides the most comprehensive results and is the recommended approach to searching the Service. Results are presented on a Summary Page where users can follow links or select tabs to easily navigate through all the search results to find the information they are looking for.

Collection-specific searches can be narrowed and conducted across a single web collection or a specific database within a collection. By linking to MSDS plus CHEMINFO, CHEMpendium™, RTECS®, OSH References, and Canadian enviroOSH Legislation search pages from the Web Information Service home page, users can conduct a search that will produce search results for that collection only. Searches can then be modified directly from the Search Results page.

Advanced searches, allowing "field-specific" searching, are available for a number of databases by following links on the collection-specific search page. [More about...]

Search Results

Clear, organized search results pages allow you to:

  • view a summary of the search results at the top of each page
  • switch between collection results using tabs and/or links
