Other things to try searching on anything CIO related, Corporate Strategy,
Value, IT Management, Enterprise Portfolio Management. Check HBR, MIT
Sloan Management Review, McKinsey Quarterly. Check Bitpipe for white papers
http://www.bitpipe.com/. Check out
META Group, Gartner, Forrester, Jupiter - there is some free stuff on
their websites.
Two items that may assist you are (If you have access to them):
Faulkner Advisory for IT Studies
A good journal database, e.g., ABI Inform, or Ebsco Business Source Premier
You would have to pay for any full text documents
that you get from these web sites but they might be useful. Two words
of warning, their search engines are kind of clunky and their reports
can be very expensive but they do have useful information. If you have
access to Dialog/Datastar you could check the computer databases and market
analyst databases for information. Also if you have access to Dialog's
Profound service you can search the reports from a number of market analyst
firms in one database. They you can buy the full report or in some cases
buy just the section of the report that is of interest. There are also
other web sites that index the market analyst reports and sell them such
as MindBranch (http://www.mindbranch.com)
and MarketResearch.com (http://www.marketresearch.com).
These sites sell only the full reports, you can't purchase sections of
reports.
