DeLillo readers may enjoy a new podcast called Don DeLillo Should Win the Nobel Prize, which is run by Jeffrey Severs and Michael Streit. You can also find it via Instagram @delillopodcast. The podcast debuted in September 2023, coming about one per month, and they plan to cover all the novels in chronological order.
And: in April 2024 I did an interview with Jeff and Mike, and it is now released to the world as DDSWTNP - Episode 12.The Don DeLillo Society was formed in 1999 and invites your participation. There is a Facebook page for the Don DeLillo Society, which lists events and news of interest. Also a devoted Don DeLillo Society website is still up, and includes an excellent guide to DeLillo literary criticism, and much other information of interest to DeLillo fans.
The New York Times has a nice collection of their reviews of DeLillo, along with links to articles by and about The Man. They also have this page which links to articles that mention DeLillo.
It's no surprise that Wikipedia has a growing entry for DeLillo.
Looking for the DeLillo-esque? Check out the DeLilloid blog for topical bits that seem like they could have been written by the man himself (or as the subtitle puts it, 'Watching life imitate the work of Don DeLillo').
Stephen Burn wrote a very good short overview of DeLillo's life and work for the Literary Encyclopedia, which can be found here.
Another site that is about DeLillo's most popular book: White Noise on White Noise (now on Wayback link).
April 1, 2009: I've learned that a public-service minded individual going by the handle of the Donologist has been busy adding radio interview clips onto YouTube. Enjoy.
