MINI-THREAD: Since the #1619Project creators are still insisting that the deleted line was not an "official" part of the project, here are documented instances where the @NYTimes published its claim about a reframing of US history with "1619 as our true founding"

First, the NYT sent out this phrasing as part of its daily subscriber email on August 17, 2019 as its header to introduce the 1619 Project. A static copy of that email may still be found here: https://static.nytimes.com/email-content/MA_16255.html

Second - on August 16, 2019 the NYT appended a blurb with the now-deleted passage onto an interview with Lauretta Charlton, editor of its Race/Related newsletter.

Third - on the week that it published the 1619 Project, the NYT also used the now-deleted passage in an article announcing the launch of an accompanying K-12 curriculum from the Pulitzer Center.

Fourth, the NYT used the now-deleted line to announce the 1619 Project in its August 15, 2019 classroom "Learning Network" supplement. https://www.nytimes.com/2019/08/15/learning/summer-reading-contest-week-10-what-interested-you-most-in-the-times-this-week.html

As these links demonstrate, the now-deleted language was not only a part of the original 1619 Project - it was also part of the paper's coordinated effort to direct readers to the project across multiple different channels.
