For many studies within the CU Data Collection, access is restricted to Columbia University users and terms of use apply. Terms of use are specific to the source of a data study and users have the responsibility to make themselves aware of these terms. The terms can usually be found in the documentation that accompanies a study. Depending on the source, the terms can cover such issues as:

• type of use (instructional and research versus commercial use),
• acknowledgment of the principal investigator, data producers, and data distributors,
• a prohibition against attempting to identify the participants in study,
• a prohibition against redistributing or selling the data,
• a prohibition against re-engineering software that accompanies data.

Specific examples of such policies include:

• ICPSR Standard Terms of Use Statement
  Some studies at ICPSR have more restrictive terms; always read carefully.
• Roper Center's Responsible Use Statement
