| IRS990/Desc | 0 | The Library's collections include unique subsurface data, plus historic and artful maps. The data is used by geoscientists pursuing exploration ideas and researchers associated with museums and universities and by the public. The data is used to publish new understandings of the subsurface and geologic history of the earth. We engage the public in curating and viewing our collections through events (Map Mondays and Data & Drinks). Library staff actively curate new donations and work to organize the data for public use. We also received over ten research requests for data only available in our Library. Volunteers contribute to scientific knowledge through analysis and organization of data. |
