Linking to E-Resources at Purdue Libraries: Home

Stable links


The best way to share scholarly resources is to use "persistent links" to the libraries subscriptions, rather than sending PDFs.  Sharing links:

  • is legal and in compliance with US copyright law
  • provides credit to the original author and journal
  • provides accurate usage statisics to the Libraries

The terms "persistent link" or "persistent URL"  is a Web link that remains stable and unbroken over time.

This guide will assist in creating "persistent links" for

  • "virtual" coursepacks,
  • course web pages,
  • research guides, and
  • other applications.
