100 Thousand Poets for Change was initially conceived by Michael Rothenberg and Terri Carrion in March, 2011, as a worldwide set of events to take place simultaneously on September 24, 2011.
The poems in the pdf were selected from The John MacKay Shaw Collection, which consists of books, works of art, manuscripts, catalogs and ephemera related to childhood.
The organization's central office then publicizes the event through its web site, social media outlets, and conventional press releases.
Local organizers, then, have full control over the style and structure of their events—their only obligation is to register their event with the main 100TPC web site.
Each year, the central organizers pick a Saturday in September as "100 Thousand Poets for Change Day" and focus their publicity on that date.
