The IQSS Dataverse Network contains studies from large archives as well as studies from small dataverses owned by individual researchers. The owner of each dataverse chooses whether or not to share the study information and data files. We encourage everyone who creates a dataverse to make the data public, but this of course is not always possible due to confidentiality or personal reasons.

Here are some of the large dataverse in our Dataverse Network that hold data from known archives:

• Murray Research Archive dataverse: This dataverse has a mix of studies for which the data are restricted for use. Information on data access can be found on the Murray Archive dataverse (Link to MRA DV: http://dvn.iq.harvard.edu/dvn/dv/mra).
• ODUM dataverse: Studies in this dataverse are harvested from the ODUM Dataverse Network (Link to Odum DV: http://dvn.iq.harvard.edu/dvn/dv/odum)
• ICPSR dataverse: The data in this dataverse are accessible only to Harvard and MIT affiliates. The study information is available for viewing by everyone (Link to ICPSR DV: http://dvn.iq.harvard.edu/dvn/dv/icpsr).
• Roper dataverse:  All study information is available to the public, but the data files are not accessible through this dataverse. To access the data, follow the original source link in the study (Link to Roper DV: http://dvn.iq.harvard.edu/dvn/dv/roper)
• Data Web:
• N.A.R.A:This dataverse contains the numeric data holdings from the National Archives and Records administration of the United States. Most holdings (those which are not sensitive) are available to the public with a nominal copying charge. To order a specific study, use the links in the "conditions" and abstract for that study (Link to NARA DV: http://dvn.iq.harvard.edu/dvn/dv/nara)

Most other dataverses in the IQSS Dataverse Network have public data. If a study has restricted data, you can contact the administrator of that dataverse (Contact Us) to find out more on how to access the data, if possible.

Other Dataverse Networks (independent of the IQSS Dataverse Network) might have different conditions on their data access. Consult those Dataverse Networks directly if you are interested in their specific data. Examples:

• ODUM Dataverse Network
• Thailand Dataverse Network
