     • 190+ Engineering Disciplines                       • Science, social sciences, health science, etc.

2. Search leverages index data from                  2. Search based on Google Algorithm leverages
   Engineering Index Thesaurus to refine,               citation data (link from a result to that article‟s
   expand, and link searches by index terms             citations)

3. Peer-reviewed journals, hard-to-find              3. Content available online, including peer-
   conference papers, and trade publications, plus      reviewed paper abstracts, theses, books,
   historical content not available anywhere else       scientist homepages, public patent records, etc.

4. Comprehensive coverage of Engineering             4. Comprehensive coverage of Engineering
   literature from 1884 – present                       literature from 1990’s – present

5. Trusted by top engineers and researchers at       5. Trusted by millions of people searching the web
   leading universities, corporations, and              every day
   government facilities

Engineering Village – Record Tagging

   • Search   other users‟ tags to gain new perspectives
   • Share   tags with other users
   • Organize   records of interest for yourself and groups
How Record Tagging Works

                           •   Assign meaningful keywords
                           •   Choose with whom to share:
                                • Public = All Engineering Village users can see the tags
                                • My Institution = only people from the users’
                                  organization can see tags
                                • Private = Only the user can see their tags
                                • Or create groups to share tags with members

                           •   Tag externally to 2collab or del.icio.us



                                •   2collab: tag and share records in an environment
                                    specifically designed for scientific researchers
                                •   Manage tagged content from Science Direct,
                                    Scopus, and EV in one central location
