Link Builder

Use the Link Builder to create stable links to the library’s online resources that UNC faculty, staff, and students can access on- or off-campus.

After entering your stable link or DOI, the Link Builder adds the UNC proxy prefix ( The proxy prefix will prompt you to log in with your Onyen to access the library’s resources from off-campus.

Using the Proxy Prefix

The location and type of link or DOI will vary from database to database. If the Link Builder above does not work for you, you can copy and paste a link or DOI at the end of the proxy prefix. Follow these directions for the type of link or DOI you are using:


Databases will use symbols to show that a permalink option is available. The symbol is of two connected chain links. By clicking on this symbol, or one similar, a pop-up window will open that contains the link. Copy and paste this link.


DOI, or Digital Object Identifier, provides a unique identification for objects of any type. These will look like a series of numbers with punctuation breaking up the various sets (e.g. doi:10.1000/182). You will need to add to the front of the DOI then connect the URL that you have created to the proxy prefix.

Stable Links

These are permanent links not represented by a symbol. Databases like JSTOR use these rather than a permalink or DOI to provide persistent links to their articles.

Bookmark or Cite

If you are unable to find any of the above options for the article you are looking at, try the Bookmark or Cite options. Selecting to bookmark the article will typically pop-up a window that shows the persistent link to the article. If bookmark is unavailable, look for a cite option. This option will sometimes need you to save a text file (.txt) to your computer, but will include a link to the article. Since the link would appear on a reference or works cited page, it is the permanent link to the article.
