As part of ongoing platform improvements, HeinOnline will be transitioning to a new domain on Wednesday, June 10, 2026. To ensure uninterrupted access, some institutions may need to update their proxy server configurations before the transition date.
Current domain:
heinonline.org
New domain (forthcoming):
access.heinonline.com
Who Needs to Take Action?
- OCLC EZproxy Cloud customers and customers without a proxy server do not need to make any changes. No action is required.
- Customers using other proxy configurations will need to update their proxy stanzas to ensure continued access. We will provide detailed instructions between May 26 and June 3, 2026 to guide you through the process.
MARC Record URL Updates
Libraries that already have Hein MARC records loaded into their catalogs may request updated MARC files containing the new HeinOnline domain URLs.
Please note that existing/old URLs in current MARC records will continue to redirect automatically to the updated domain. This means that existing catalog links should remain functional during and after the transition.
Need Assistance?
If you have questions or need help preparing for this transition, HeinOnline Support is available to assist.
