Terms and Condition

Dewey Data has some specific terms and conditions which differ from most MIT Libraries databases:

  • Users must be must be a current faculty or staff member or a currently enrolled student to use the data
  • Users can use the data in collaboration with up to ten (10) non-MIT professors from up to three (3) different universities as long as they are part of an authorized research team with a MIT faculty member and agree to comply with these terms of use, or are covered by a Dewey Data license.
  • If MIT’s license to Dewey Data ends, users must delete any data downloaded from Dewey Data, unless you need it for a publication that was accepted for publication at the time that our subscription ended,  or if you are required by a funder or open science mandate to keep the data for retention purposes. (Dewey Data may ask for documented proof.)   
  • Users cannot compare/verify/evaluate Dewey’s data with other sources and publish those findings elsewhere.
  • Users cannot publish the data in raw form. Users may only publish a minimal amount of raw data as part of a summary of insights derived from the data.
