There may be many reasons why you might want to link to an electronic resource rather than downloading the content and copying it. The primary reasons are copyright guidelines and licenses.

Some library resources are licensed from the resource provider. The license usually spells out what kinds of uses are and aren't permitted when downloading/copying content from the resource. Since it's sometimes difficult to find and interpret this license information, it may be safer and easier not to copy material, but rather to link to it.

When a resource is not covered by a license, then copyright law governs the use of copyrighted material. Copyright guidelines require that when using materials that are protected by copyright without permission from the copyright holder, that the user must apply fair use principles. The fair use of a copyrighted work, including such use by reproduction in copies or phonorecords, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. However, whether or not you are within the boundaries of fair use depends on the facts of your particular situation. Because it requires some time and interpretation to determine whether your use is a fair use, it may be safer and easier not to copy material, but rather to link to it.

Linking to electronic resources rather than copying from them also provides NSU Libraries with more accurate usage statistics. The Library collects data on how much resources are used. If you download an article and then provide copies of it, the uses beyond the initial download will not be counted. The library decides whether to continue to subscribe to resources based on several factors, not the least of which is usage. So, if all uses are not able to be counted, the usage statistics will be lower than actual use and continuing a subscription to the resource may seem unjustified.

If you create them correctly, yes. When off-campus, users may access library resources via Off Campus Proxy. Many NSU Libraries resources (e-journals, e-books, and databases) are restricted to the NSU network address (IP address). Users connecting to library resources with outside Internet service providers need to sign in in order to be authenticated as belonging to the NSU community. Otherwise, the resource providers won't be able to determine that the user is validated to use the resource.

Therefore, the persistent links that you create and the URL will prompt the user to log in if they are off-campus. If the user is on-campus, the user go directly into the resource.

Yes, links to EBSCO Full Text eBooks, ProQuest Nursing & Allied Health audio and video materials, and CINAHL eBooks should not be permalinked.

EBSCO eBook Collection

ProQuest Audop & Video Collection

CINAHL eBooks ISBN =978* AND Limiter=eBooks

For instance, the PubMed articles and many of the National Institute of Health resources have a unique PMID number so you don't have to add that in.

How you determine what a persistent link should be will depend upon the resource provider and how their platform is built. Here are some tips and features to look for:

• In Ovid resources, when you are viewing the resource, look for a link that says "Email jumpstart." This will generate a persistent link that could be copied and used.
• Look for a link to "Email article." This will usually create a persistent link. NSU uses a spam filtering service, to scan links in emails from external senders. It is possible that the link in the email will begin with https://urldefense.***followed by a long string of characters. This is not a persistent link. Please contact NSU Libraries for further assistance if this occurs.
• Some databases have a URL listed next to the heading "Persistent link to this record."
• Some databases have a link that says "Get a Link."
• Some resources have a link that says "DOI Bookmark." A DOI is a Digital Object Identifier and that will uniquely identify an electronic document permanently.
• Contact NSU Libraries for help with creating persistent proxied links to individual ebooks licensed by MCW Libraries.
