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.

MeasuringWorth is a service for calculating relative worth over time. The data have been created using the highest standards of the fields of economics and history, and they are rigorously refereed by the most distinguished researchers in the fields. Beginning with the United States and United Kingdom and following with Japan and China, the authors intend to keep growing the database. Includes calculators for annualized growth rates, relative values, conversion, purchasing power, inflation rates and stock growth rates.
