e-Resources in Teaching: Find the permalink to a resource

A quick introduction to integrating e-textbooks into the USU curriculum.

Method 1: Using PowERSearch to get e-book links

  1. Search PowERsearch for the item
  2. Click on title
  3. Click on Permalink icon
  4. Click ‘Copy Permalink to Clipboard’
  5. Paste permalink URL into desired documentation

A search in PowERSearch retrieves an item, with an arrow pointing to the permalink icon/text

Method 2: Formulating links to e-books and other resources

Using the Proxy Prefix

As an alternative to using the PowERsearch Permalink method, you may formulate a link (URL) to most LRC e-resources using the following method.

LRC link = Proxy Prefix + the actual resource URL

  • For USU Main users: LRC link = + [the actual URL]
  • For USU PDC users: LRC link = + [the actual URL]

In other words, if you have a link to a resource -- which could be an e-book, e-journal, specific e-book chapter, specific e-journal article, database, or other LRC-subscribed website -- simply add the Proxy Prefix before the link.


  • A collection/database: ClinicalKey
    • The actual URL to ClinicalKey is:!/
    • The LRC link for USU Main users is:!/
    • The LRC link for USU PDC users is:!/
  • A specific e-book: Robbins & Cotran pathologic basis of disease (10th edition) 
    • The actual URL:!/browse/book/3-s2.0-C20160040871
    • The LRC link for USU Main users is:!/browse/book/3-s2.0-C20160040871
  • A specific e-book chapter: Robbins & Cotran pathologic basis of disease (10th edition), chapter 8, "Infectious diseases"
    • The actual URL:!/content/book/3-s2.0-B978032353113900008X
    • The LRC link for USU Main users is:!/content/book/3-s2.0-B978032353113900008X

Note: Not all e-book providers have the capability to link to specific e-book chapters.

Prefix Is Preferred

When a user visits an e-resource with the proxy prefix, the URL will likely resolve to a different format, with the proxy information placed as a suffix after the top level domain (e.g. the .com), and periods in the resource URL are replaced with dashes.

For example:

  • When a user visits ClinicalKey through the USU01 proxy:!/
  • ...the URL bar resolves to:!/

While the second format will usually work, it is not preferred. When a user visits a website using the second format, it bypasses the proxy's statistics gathering. In some cases, the LRC relies on usage statistics to determine which resources to continue subscribing.

To ensure that usage is counted properly, the LRC recommends always providing the prefix format to users.

The Proxy Facilitates Authentication

When you want to provide a link to an e-resource to a USU user (faculty, staff, students), it is important to provide the LRC link. Do not provide the resource URL alone. That is, it is important to include the Proxy Prefix. The proxy is how LRC facilitates authentication -- it allows the resource's website to know that the user is indeed affiliated with USU, and therefore should be allowed to access the resource.

 When a user visits a resource with the Proxy Prefix in the URL, the user may be asked to log in with their USU Single Sign On account. This will authenticate the user.

Method 3: Ask LRC Staff

Besides using the PowERsearch method or constructing the URL yourself with the LRC Proxy Prefix, you may simply ask LRC staff for assistance!

Send us a list of resources (books, book chapters, journals, journal articles, databases, etc.) and we will help you find the proper URLs to use.
