Linking to Copyrighted Materials

If you publish your work online, you are already in the practice of using links to enhance your content. The Web's basic architecture relies heavily on the ability of webpages to link to other pages to allow natural navigation between related content. It is hard to imagine the smooth functioning (or even continued existence) of the Web without hypertext links that act as a reference system identifying and enabling quick access to other material. Fortunately, courts generally agree that linking to another website does not infringe the copyrights of that site, nor does it give rise to a likelihood of confusion necessary for a federal trademark infringement claim. However, different kinds of linking raise different legal issues, and the law is not entirely settled in all of these areas. Moreover, some linking activities may expose you to liability for contributory copyright infringement or trafficking in circumvention technology in violation of the Digital Millennium Copyright Act (DMCA).

Types of Links

Deep Linking: The most straightforward case is so-called "deep linking," which refers to placing a link on your site that leads to a particular page within another site (i.e., other than its homepage). No court has ever found that deep linking to another website constitutes copyright or trademark infringement. Therefore, you can link to other websites without serious concerns about legal liability for the link itself, with the exception of activities that might be contributory copyright infringement or trafficking in circumvention technology (discussed below).
