“For me, [EV] works better than Google. Because Google comes up with a whole bunch of other stuff that is completely not relevant”*

* ”Elsevier Engineering Village Attitude and Usage Study Among Corporate Engineers” September 2008

Evaluating Articles’ Relevance is Time ConsumingNeed insight to move research forward

Google Scholar: All Subjects

(525,000 results)

Compendex (158,584 results)

Sample Search: “Metallic Compound”

• Compendex on EV:

• Leverages indexing to offer sorting, filtering, and linking options

• Google:

• Impossible to gain insight with so many results and no way to organize

Google Scholar: Limited

(23,600 results)

• Sort by relevance, date, author, source, title

• Quickly filter by fields including author, author affiliation, classification codes, controlled vocabulary, publisher, date, source type, and more

• Set up alerts, save searches, save records, export result data

• Tag records and create groups to share and collaborate

• Link to full-text on publisher site from results or record view

• View all records or “recent only”

• Link to more by same author

• Link to article citations

• Link straight to publisher sites – no detailed record

“Google is like a large library where all the books are piled on the floor. You are just hunting through hoping you can find what you want. You kind of know

you’re in the general section and that’s about it.”*

Insight and Organization save valuable time

Search Term: Metallic Compound

* Limited to “Engineering, Computer Science, and Mathematics”

• Google Scholar: Broad Search• Volume of results is useless for targeted research

• No focus on specific discipline or organized results

• Result: information overload

• Google Scholar: Limited Search

• “Engineering, Computer Science, and Mathematics” still too broad/vague for precise engineering focus

• Yet results too limited to be sure nothing is missed

• Compendex• Comprehensive, trustworthy engineering coverage

• Indexing ensures results relevant for engineering

• Leverage indexing for organization options

Individual Record Details for efficient discovery and innovation

• Metadata from engineering indexing

• Consistent format and data across results

• Link from all record views to full-text on publisher sites

• Hyperlinked data uncover relationships in published research

• Highlighted terms show relevance at-a-glance

• No detailed records; often just record title

• Inconsistent format

• Link straight to publisher site without any further information

• Makes organizing, tracking, and identifying relevance near impossible

• Result details put record in context of greater research question to bring you to solutions faster

Compendex Detailed Record

• More than 10 million records

• Detailed Source List available

• Over 5,600 peer-reviewed journals, trade magazines, and conference proceedings indexed annually (selected by subject experts)

• Coverage dating to 1969 or to1884 when purchased with the EI Backfile (additional 1.7 million records)

• Updated weekly

• Over 650,000 records added annually

• Billions of records across disciplines; no exact record count available

• No source list; no way to know what is covered

• Less coverage of trade publications and conference papers

• No disclosure of dates covered, when records are added, etc.

• Doesn’t own or have control over content so no regulation of errors like misspellings, incorrect spacing, etc.

Coverage Details Detailed CoverageFocused Research vs. Broad Overview

Coverage Overlap

• Selective in scope; only cover the most relevant content

• May not cover every volume of a journal

• May not cover every issue in its entirety

• Indexes content available only in print, including historical records not available anywhere else online

• Sources are not expertly or selectively chosen for inclusion; Don’t disclose how sources are decided

• Only covers about 50% of the trade publications and conference papers in Compendex*

Google’s coverage of trade journals and conference proceedings is lacking – both are essential resources for staying up-to-date and well
