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.
