SNR maintains a walk-in and on-line store (http://nebraskamaps.unl.edu) where customers can purchase SNR and US Geological Survey (USGS) publications. In addition, the store is Nebraska's only USGS Earth Science Information Center (ESIC) outlet. As such, it is authorized to sell USGS products, including complete topographic map coverage of Nebraska. The walk-in store is open 8 a.m. - 12:00 p.m. and 1:00 p.m. - 5:00 p.m., Monday - Friday, closed weekends and major holidays. The on-line store is open 24/7. Those receiving funding from SNR receive a 30% employee discount on their purchases. Items bearing the N logo already include the employee discount.
