Access to Patterns Dataset


I get a few questions when exploring Dewey Platform:
(1) I am not sure if my university has subscribed to the Dewey platform, how can I download “Patterns” datasets using my academic account for free?
(2) Is it possible that I can get access to previous “Patterns” datasets for New York prior to 2018?

Please write to if you were previously accessing Patterns data for free and need a historic file.
