University courses may include library resources as required or supplemental course readings. Students, as well as faculty, access library resources in the course room via a persistent URL or permalink. Permalinks are exactly what they sound like—durable links that connect directly to a full-text resource without prompting for login or breakage in the link. This page provides an overview of permalinks, in addition to instructions on capturing permalinks depending on which library database you are utilizing.
As a faculty member, you can capture permalinks to share with your students. You can share permalinks to specific resources and, in some instances, you can share permalinks to sets of search results. There is a corresponding page on Persistent URLs that you can share with your students.
Finally, if you or your students encounter broken permalinks in the course room, please report the broken link to the Library at library@ncu.edu.

Bad Request Error when Accessing a Library Resource
A Bad Request error can be attributed to an improperly formatted link to a resource. The NU Library can assist with locating the resource and providing a properly formatted link to access it. If you have received this message in error, please contact the NU Library directly by calling 888-628-1569, by texting 928-550-6552, by emailing library@ncu.edu, or by chatting with us during live help hours.
A persistent URL (PURL) is a durable link that connects users directly to an article, eBook, or other item in our Library.
PURLs can be useful when creating syllabi, bibliographies, and other research tools. PURLs also help us remain in compliance with copyright rules when linking to Library resources.
Each Library database has a different process for capturing PURLs. This guide addresses the unique process for each database.
Links are usually persistent but NOT necessarily permanent. PURLs may become obsolete over time, especially as our Library database subscriptions change year to year. Make sure to test links on a routine basis.
Copyright rules are no exception for PURLs. Make sure to cite the source when linking or downloading Library resources.
Not all database vendors offer PURLs. This guide covers all databases which do offer PURLs.
Unfortunately, not every Library database supports persistent linking. The following databases currently do not support persistent linking: ETS Test Link, ReferenceUSA, Ulrichsweb, Web of Knowledge, Westlaw Campus Research. Please contact the OERCS Librarians (oer@nu.edu) directly for alternative solutions for course integration.
If a PURL is producing an error or you are unsure how to capture it, please contact the Library at library@ncu.edu or 888-628-1569.
