A DOI (Digital Object Identifier) is an unique alphanumeric string assigned to digital objects and will not change over time.
Persistent links should remain consistent as long as the library maintains a subscription to the database. However, some persistent links have expiration dates, and vendors occasionally remove content without notifying the library, so it is important to test your persistent links regularly and update as needed.
To ensure that you will always be able to find your online materials again, and to conform to copyright restrictions, include the article citation as noted in the Copyright Information.
In order for persistent links to work from off-campus, the Library's proxy server prefix must be added to the beginning of the persistent link provided by the database. Please refer to the Off-Campus Access Information (Proxy) below.
Persistent links are links that remain constant. They are provided by many online library databases to ensure consistent access to full-text online articles, electronic books, etc. Persistent links to resources will remain active as long as the item is included in the database, or as long as the library maintains a subscription to the database.
Please refer to the Finding Persistent Links section of this guide.
Other names for persistent links include: permalink, document link, copy link, article stable URL, and bookmark.
Copying and pasting links directly from the address bar on a webpage can be problematic. Often these links are temporary and will not link back to the original source. Using a permalink makes getting back to an article much easier. Permalinks can be added to your Canvas site, webpage, library electronic reserves, email or any other place you use a URL.
Linking directly to articles in Library subscribed e-resources has the advantages of being copyright compliant and cost effective. Using permalinks to connect readers to articles also creates usage statistics that the Library examines when deciding whether or not to continue a subscription. Reading a PDF that was loaded onto a site does not create usage statistics. Thus, a journal that should be garnering high usage statistics will end up showing very little usage.
Be aware of copyright restrictions when linking to library materials, or electronic resources licensed by the library.
