Linking to Electronic Resources: Creating Durable Links: Getting Started

​How can I create a durable URL quickly?

Does the article have a PMID (PubMed Identification #)?

• http://himmelfarb.gwu.edu/pmid/30931605
• Tip: test link.  If it doesn't work well, link directly to provider/publisher page.

Does the article have a DOI (example: 10.1001/jama.2017.9477)?

• http://himmelfarb.gwu.edu/doi/10.1001/jama.2017.9477
• Tip: test link.  If it doesn't work well or get you to the full-text article, check Himmelfarb Library's holdings for the journal and link directly to provider/publisher page.

How can a link to an e-book or e-journal be created using an ISBN or ISSN number?

• E-Book example:  https://himmelfarb.gwu.edu/isbn/9780071843249
• Journal example:  https://himmelfarb.gwu.edu/issn/00987484 

Is the full-text article available via EBSCO, Ovid, or Proquest?

• Use the full-text links provided within the article or book:
  • EBSCO: Permalink
  • Ovid: Email Jumpstart
  • Proquest: Document URL
• Do NOT use the displayed URL; the displayed URL will work for only a short period of time.

What is a durable link?

• A link that will consistently deliver access to an e-journal or e-book regardless of if the user if on- or off-campus
• A link that connects the user to the copy of an e-journal or e-book provided by Himmelfarb Library

Why should I use durable links instead of PDFs?

• Durable links connect students to required and recommended readings and do not require faculty to obtain copyright permission. 

What does a durable link look like?

• A durable link combines the proxy prefix which hooks the link into Himmelfarb Library: https://proxygw.wrlc.org/login?url= with a stable URL for the item (example: http://www.nejm.org).  The two components are combined with no spaces:  https://proxygw.wrlc.org/login?url=http://www.nejm.org
• Durable links may also be created by using a standard number from the item to create a link: the PMID for PubMed articles, the ISBN for books, and the ISSN for journals.​
  • PubMed article example:

https://himmelfarb.gwu.edu/pmid/25766056

• DOI example: 

http://himmelfarb.gwu.edu/doi/10.1001/jama.2020.7709

• E-Book example: 

https://himmelfarb.gwu.edu/isbn/9780071843249

• Journal example: 

https://himmelfarb.gwu.edu/issn/00987484 

If an e-book as limited simultaneous users online, can I create a PDF and load it to Blackboard?

• No: creating a PDF and loading it to Blackboard may violate copyright as this could affect the sale of the original work.   Please contact the Himmelfarb Library Reserves Department by email mlbrsv@gwu.edu or telephone at 202-994-2962 so that we can assess options. 

Where can I learn more about copyright and 'fair use' of materials?

• The Fair Use Checklist may be a useful place to start.
• Himmelfarb Library's Copyright Research Guide may also be useful. 
• Blackboard Copyright Chart.

How many users/copies/seats are available for specific books or articles?

• Most electronic resources available via Himmelfarb Library provide 'unlimited users' access, however some resource permit a fixed number of concurrent users.  
• To ensure adequate access for your students, please check with Ian Roberts (imroberts@gwu.edu or 202-994-3685) prior to assigning a reading to fifteen or more students.
