Numeric Data Archives

The Penn Library maintains subscriptions or memberships to several data archives, which provide numeric data sets to subscribing institutions at little or no cost. In most cases, data archives require mediated access to data sets.

Procedures for obtaining numeric data from individual archives is provided here.

NB. This page is temporary and will change as the Penn Library enhances its own numeric data identification and description tools.
