The guidelines below are intended to help users determine whether or not their use of OCW materials would be permitted by MIT under the "non-commercial" restriction. Note that there are additional requirements (attribution and share alike) spelled out in our license. 4:Commercialization is prohibited. Users may not directly sell or profit from OCW materials or from works derived from OCW materials. Example: A commercial education or training business may not offer courses based on OCW materials if students pay a fee for those courses and the business intends to profit as a result. Determination of commercial vs. non-commercial purpose is based on the use, not the user. Materials may be used by individuals, institutions, governments, corporations, or other business whether for-profit or non-profit so long as the use itself is not a commercialization of the materials or a use that is directly intended to generate sales or profit.
