If a single database isn't working, please email us at ask-a-question@unl.edu and we will try to fix it ASAP!
If all the library's databases are down, there is a problem with our proxy server.
If you are on-campus, just remove the first part (http://libproxy.unl.edu/login?url=) of the database's URL - it should recognize that you are on campus and still let you into the database.
Example
Original URL: http://libproxy.unl.edu/login?url=https://www.nature.com/nature/volumes
Workaround URL: https://www.nature.com/nature/volumes
If you are off-campus, you will be unable to access the databases this way. You can still request articles through Interlibrary Loan in the meantime and we will deliver them to you as soon as we can!
