A few weeks ago, I landed a well-known agent who has been in the business for over thirty years. While I have seen several of his deals with major publishing houses posted in PM, he doesn't have a website and doesn't seem to flaunt his agency. He keeps a low profile, it seems. He only takes referals from clients, and it appears he runs his operation solo.
His e-mails are not longer than one or two sentences. He's a mystery.
That begs the question: Could a successful literary agent thrive without having a paramount Internet presence?
Does Phil Spitzer have a website?
A cursory google didn't turn up anything. Phil is probably THE guy for mysteries, and a darn nice man to boot.
I'm sure there are others but I'll let the Snarklings fetch some more examples.
