What is happening to the URL linking syntax of IG Publishing databases?

The provider IG Publishing has switched the linking syntax URL to HTTP secure (HTTPS) protocol for all of its databases.

Therefore, we will begin changing the title-level linking syntax in the Knowledgebase as the provider updates the title list. The content of the IG Publishing databases will remain the same.

This change will begin on May 1, 2026:

• Before May 1, 2026: http://portal.igpublish.com
• After May 1, 2026: https://portal.igpublish.com

Click here for the affected databases.

Action you need to take:

• Make sure that either https://portal.igpublish.com or *.igpublish.com is included in your proxy configuration before May 1, 2026.
• If you are a 360 MARC Updates client and have requested the custom specification that adds direct URLs to MARC records, you can expect to see some change records when you get your MARC records after May 1, 2026.
