Secondary research refers to data that already exists. Many government websites contain free or lowcost information about demographics and markets (see the section above on statistics). Generally speaking, there are no free sources of market research reports published by commercial firms such as Gartner, Frost & Sullivan, and Datamonitor. You can often find useful market information on industry and professional association websites.

MarketResearch.com
Marketresearch.com is a searchable database of market research reports covering all industry sectors, both domestic and international. The site offers free searching, abstracts, and tables of contents, but the actual reports are fee-based, often costing thousands of dollars. You can sometimes buy “by the slice” to get specific pieces of a report.

Mindbranch
Mindbranch is similar to MarketResearch.com in that it aggregates syndicated and custom industry research from 350 independent research firms through a searchable interface. Searching is free; the actual reports are fee-based. Description and table of contents are available for most reports, and purchased reports are downloadable in PDF format.
