Frequently Asked Questions


How do I activate my institution's site license?
New England Journal of Medicine customers will receive an email that contains account information and customer number. Use the link provided to begin the activation process. Administrators will create their own personal My NEJM account as part of the activation process. Site license administrators are responsible for maintaining up-to-date information on their institutional accounts (IP addresses, branding, and link resolvers) through the Institution Administration Center.

NEJM Journal Watch Online customers will have their account activated on their behalf and will receive an email with account information when this is complete.

Can I use the same email address to administer my site license account and get access to as an individual?
Administrators who currently have an administrative account for their institution and have registered as an individual using separate email addresses should contact us to combine them under one email address.
I cannot use IP-based access. Do you offer any other access methods?
NEJM Group supports both OpenAthens and Shibboleth as access methods for institutions with a site license or archive access. More information on OpenAthens and Shibboleth can be found below.
I’m having trouble accessing
Our publishing platform may not support the browser you are using. TLS1.0 has been disabled by our platform provider due to PCI compliance; current browser versions do not support TLS1.0. You may use any one of the supported browsers (such as recent Chrome, Firefox, Safari (desktop and mobile), IE11, Android, etc.). Versions of Internet Explorer older than IE11 are no longer supported because they are not security compliant.

NEJM has transitioned from HTTP to HTTPS. What does this mean for libraries?
The website has migrated from HTTP to HTTPS hosting to increase online security. While access through OpenAthens and Shibboleth will not be impacted, maintaining remote access through a URL rewriting proxy server such as III WAM or OCLC EZProxy will require configuration changes.

Required changes include:

  • ensuring that an SSL certificate has been installed
  • updating your proxy server’s configuration with the newest NEJM database stanza found here on the OCLC site.

If you have EZProxy hosted service, OCLC will automatically make these updates. If you use the EZProxy standalone service, your IT department should be able to make the required changes. For additional help, contact OCLC Customer Support in your region.

URL redirects will remain in place indefinitely. Redirects for services such as A To Z Serials Access will also happen automatically, but we recommend that you manually update links to reflect the change to HTTPS.

Browsers which are compatible with HTTPS include:

  • Internet Explorer 10 and later
  • Google Chrome
  • Mozilla Firefox
  • Safari

I am a site license administrator. Do you have a guide for managing my account?
Yes, please download our Guide for Institutional Administrators.
How do I verify or update my email address, password, or personal information?
As an administrator, you will have your own My NEJM account. Once you are signed into, look for the link to My NEJM at the top right of the page. There, you will also see a link to My Account; this will bring you to your account summary.

Please contact us for further assistance with your password.

Help with IP Addresses
An IP address is the numeric address of a computer connected to the Internet. On most networks, each computer has its own IP address. An IP address is not the same as a domain name or an email address. By inputting your institution’s IP addresses, you are uniquely identifying the eligible machines on your network and allowing access only to authorized users of your subscription.

You can add your institution’s IP address(es) within the Institution Administration Center. Note that there is a description field alongside the IP entry field. This field is optional, but you can use it to describe the IP address(es) that you are entering. For example, one IP address might be the university library, while another might be the science lab. Use the description field to distinguish between the two. Please note that if you wish to obtain usage statistics for specific IP addresses under your license, you will need to contact Customer Service.

There are a few rules that you must follow when entering an IP address:

  • All IP addresses contain 4 numeric segments, up to 3 characters long, and separated by periods (eg., nnn.nnn.nnn.nnn).
  • Place each IP address or range in the box provided, following these rules:
    • The only characters allowed are numbers, colons (:), periods (.), and asterisks (*).
    • Dashes are not accepted.
    • The allowed values for the first segment are 1-223.
    • The allowed values for segments 2, 3, 4 are 0-255.
    • You can enter a range in the last segment by using a colon (:).

To verify your IP address: Visit and note the IP address present on the page, or send us a screenshot and we can identify it for you. Please contact us if you are still having trouble inputting your IP addresses.

Help with COUNTER Reports
Who can pull reports?
Any institution administrator can pull COUNTER reports for the institution(s) for which they are an administrator. If you’re not sure how to do this on your own, please contact us for instructions.

How can I pull reports?
COUNTER-compliant usage reports are available via email delivery in XML, HTML, and tab-delimited format using the Email Reports function on the Usage Reports tab of the Institution Administration Center. You can select the time period for which you want the reports, specify any additional recipients, and opt-in to be notified when COUNTER reports become available each month.

Is NEJM COUNTER 4 compliant?
Yes, NEJM switched to COUNTER 4 reporting standards on December 12, 2013. All reports pulled after that date are in the new structure. For more information about what is new in COUNTER 4, you can consult the documentation from COUNTER here.

Reports from July 2010 – December 2013
Reports for the period July 2010 – December 11, 2013 were in the COUNTER 3 reporting format. If new copies of reports are desired for this date range, they will be delivered in the COUNTER 4 reporting format.

Reports from January 2005 – July 2010
COUNTER 3 reports from 2005 to July 2010 are available in a zip file at the bottom of the Usage Reports tab. Each report is a tab-delimited file.

You will only find partial data for the month of July 2010 in this zip file due to a platform transition we undertook on July 24, 2010. In order to get an accurate COUNTER report count for the month of July 2010, you will need to combine the July 2010 report in the zip file with the July 2010 report that is generated via email. We’re sorry for any inconvenience that this causes. Reports from August 2010 forward are available in their entirety and should be generated using the Email Reports function at the top of the page.

Please contact us with questions about your COUNTER reports or if you are having trouble accessing them.

Help with SUSHI
SUSHI (Standardized Usage Statistics Harvesting Initiative) is a way for you to collect your institution’s COUNTER reports automatically, thereby eliminating the need for you to obtain each report manually.

We provide access to COUNTER 4 reports through the SUSHI protocol, version 1.6. Learn more about how to get started with SUSHI at the NISO website.

Please contact us if you need help configuring your SUSHI client or have other questions about SUSHI.

Help with Institutional Branding
You can upload your institution’s logo and name on the Branding & Link Resolvers tab of the Institution Administration Center. The logo and name will be displayed at the top center of pages on whenever members of your community access through your IP addresses. We support up to 50 characters of text or a greyscale logo of up to 200 x 28 pixels, in .jpg, .gif, or .png formats. If you upload a logo, it will override and display in lieu of any customized text you have entered.

Contact us if you have questions or encounter trouble uploading your branding graphics.

Help with Link Resolvers (OpenURL)
OpenURL is a type of Uniform Resource Locator (URL) intended to enable Internet users to more easily find a copy of a resource that they would be allowed to access. With OpenURL, your users can link directly from citations in NEJM to resources available in your library.

Already Have OpenURL?
You can configure OpenURL directly within the Branding & Link Resolvers tab of the Institution Administration Center. Redirects are in place, so you can continue to construct your links to NEJM using one of the following configurations:
