A URL specifies the location and retrieval protocol for a digital resource on a computer network, often the World Wide Web. URLs of web pages are displayed in the address bar of most web browsers, but copying and pasting these links can be problematic. They often contain search parameters or session data that will expire and fail to link back to the resource you want.
A permanent link, or permalink, is a special type of URL intended to remain unchanged and to provide stable access to a particular digital resource. Other names for this type of link include stable URL, persistent link, and persistent identifier. When you want to link to a resource in a bibliography, Canvas site, syllabus, or email message, always look for the permalink.
DOIs are permanent, unique alphanumeric names used to identify certain types of digital content, such as a journal articles, e-books, or individual chapters within e-books (but not magazine or newspaper articles).
A DOI begins with the number 10; e.g., 10.1177/1362361315607724
A permalink may incorporate a DOI.
