The data contained on this site are available upon request with the following qualifications. We would like to know how researchers are using our data, including analyses and publication plans. Please acknowledge the data source by using the URIs provided by this site. If we feel that we should be offered participation as authors, we require mutual agreement prior to publishing the data. If the intended use of the data directly competes with our analyses, we may ask that we have first priority to submit a manuscript using unpublished data. Researchers are urged to contact the authors of these data if any questions about methodology or results arise. These data may be updated from time to time, and it is the data user’s responsibility to insure that any analyses or publications contain the most recent version of the data. In addition to informing us of plans, we kindly request preprints and updates on publication status.

Access protocol: Researchers who would like to use these datasets should contact Jill Bubier (jbubier@mtholyoke.edu) or Tim Moore (tim.moore@mcgill.ca).
