Although the Map & Data Library is physically closed, we are still available remotely and happy to help. We can conduct consultations using online teleconferencing software. Please feel free to contact us at or use our help form. We have a number of tutorials available, are still supplying software licenses, and have compiled a list of resources for working with COVID-19 data.

Please note that our computer lab is also accessible for use through remote access. See this link for more information.

Penn world tables version 5.0

Constructed by Robert Summers and Alan Heston of the University of Pennsylvania, together with the late Irving Kravis, the Penn World Tables are the definitive source for real national accounts data. The national accounts for each country, initially in their own currencies, are adjusted using detailed price data to obtain real national accounts in a common currency (U.S. dollars) across countries. These data are invaluable for making comparisons of Gross Domestic Product across countries, and for all manner of research on development and growth.
