From the introduction:
The DUNGEONS AND DRAGONS Adventurers League has been around for a few years and a number of high-quality adventure books have been published in that time frame. These books weren’t written specifically for Adventurers League. To remedy this, the Adaptation Guide has been created to make playing these books in Adventurers League as seamless of a process as possible.
...
This guide covers adaptations to the Forgotten Realms Adventurers League campaign of all official D&D releases from Wizards of the Coast available as for-sale print products and digitally through D&D Beyond and select third parties, from June 2014 (D&D Starter Set) through March 2021 (Candlekeep Mysteries). Official D&D products not mentioned here during that period are not adapted for the Forgotten Realms campaign.
