The New England Journal of Medicine welcomes linking to its Web site (www.nejm.org) provided that the following guidelines are adhered to:

• The fundamental focus of the site linking to the New England Journal of Medicine’s site should be educational in nature.

• Links should be made to the New England Journal of Medicine’s home page (www.nejm.org), or to the article’s abstract.

• Only plain text may be used to indicate the name of the New England Journal of Medicine. The name “The New England Journal of Medicine” and the seal (logo) of the New England Journal of Medicine are registered trademarks. We cannot allow use of the New England Journal of Medicine’s seal or front cover by outside organizations unless permission has been granted in advance.

• The purpose of the linkage should be to facilitate access to the New England Journal of Medicine’s content as an incidental reference (for example, as a footnoted reference to a specific article). Links to the New England Journal of Medicine should not constitute a primary component of another organization’s site.

• Material published in the New England Journal of Medicine is covered by copyright. No content published by the New England Journal of Medicine (either in print or on its Web site) may be loaded onto another organization’s site, or displayed or reproduced by any other means, without the express permission of the copyright holder.

• Material owned by the Massachusetts Medical Society (including the name, logo, cover, and text of the New England Journal of Medicine) may not be used in any manner that may give rise to the impression that the Massachusetts Medical Society or the New England Journal of Medicine is in some way endorsing or recommending a specific company, product, or service. This includes uses of the New England Journal of Medicine’s name or content by links to the New England Journal of Medicine’s Web site.

• Because of the New England Journal of Medicine’s policies for its own print and electronic formats, advertising or promotional messages must not be juxtaposed with the New England Journal of Medicine’s editorial content on the Internet (for example, through the use of “framing” or the use of advertising buttons and banners).
