Creative Commons License

Creative Commons provides alternative licenses whereby you can release some of the rights you are automatically assigned by copyright law. Creative Commons license choices specify whether you allow commercial use of the work, whether you allow modifications to the work, and whether you allow derivative works to be created based on your work.

When you submit content to the Archive, you see a Creative Commons form that allows you to identify the license to be used with the work you are submitting, so people can know what they’re allowed to do with your work. This form is optional; you can skip it if you wish to retain your full copyright.

Exclusive License

Licenses are non-exclusive by default. Licensees desiring exclusive use may license exclusivity in a particular media (Media Exclusive) or in a particular region (Regional Exclusive) or in a particular language (Language Exclusive) or in a particular industry (Industry Exclusive), or any combination or all of these four types of exclusivity.

Grey Literature

Grey literature (or gray literature) is materials that cannot be found easily through conventional channels such as publishers. Examples of grey literature are technical reports, oral histories, event brochures, school / department newsletters, etc.


Metadata provides information about a work. For example, a document’s metadata may consist of title of the work, the author, the date the document was written, keywords that describe the document, and a short summary of the document.

The UMB Digital Archive indexes the metadata so that they can be searched to locate the work.


A metric is any type of measurement used to gauge some quantifiable component of an application. For example, in the Digital Archive, metrics are used to keep track the number of the works that are entered and accessed. The metrics help analyze the usage and identify areas for improvement.

Non-exclusive License

A non-exclusive license is a grant of rights issued by a licensor to a licensee that does not preclude the licensor from granting the same rights to other licensees. For example, the author who holds the copyright of a works must grant HSHSL a non-exclusive license to distribute via and preserve the work in the UMB Digital Archive. At the same time, the author may also grant the same rights to a publisher to publish the works.

Proprietary Right

The exclusive legal right the inventor or author holds, such as patent or copyright, under which a product or works is produced, marketed or used, and protected against free competition and infringement.


SHERPA/RoMEO services are based at the Centre for Research Communications at the University of Nottingham and provide many resources including those for checking publishers’ copyright and archiving policies, and research funders’ archiving and mandate policies. Search the SHERPA/RoMEO page to find whether the publishers allow published work to be placed in a repository, and if so at what level of access.
