When Googling on Hart Literary Management, I find a "sponsored link" in the right-hand column, helpfully labeled "Hart Literary Management." That is, however, a just Google-trap:
http://management.expert-expert.com/literary-management/hart-literary-management.htm
The two links on the page are, indeed, to The Literary Agency Group con artists. No indication whatever that they're affiliated in any way with Hart Literary Management. That's just sleazy marketing by whoever put together expert-expert.com, and sleazy marketing by Robert Fletcher.
It's possible that you, or the reference book, typoed the URL and wound up at some other Google-trap.
It's possible that the agency, for some reason that seems good to them, uses Google ads. The Screenplay Agency (along with Stylus, New York Literary, Poets, Children's, and Christian) advertise heavily through Google ads.
Then again, the first link when I Google on Hart Literary Management is this:

What was the URL you used for Hart Literary Management?
This one (which I got from
this article) comes back as File Not Found.
This list doesn't have a web page, but does give an AOL email address, and a street address in Reno, Nevada.
This list has them as a WGA signatory agency, but with a mailing address in Orcutt, California. Again, no website listed.
The page for Hart Literary Management at Writer's Net is here:
http://www.writers.net/agents/185
They note that the email address is invalid. I note that the web address given is again an error 404. That one has the Reno mailing address.
I find this
here:
December 2, 2005
Binoir Films has signed an agreement with Prodigital Film Studios, a public company, to begin packaging and producing its slate of neo noir films. David Geertz of Binoir Films discovered scribe Abe Reinhartz through our network. Binoir Films has optioned his script 'Freightliner' for this new slate. Reinhartz is represented by Susan Hart of Hart Literary Management. Reinhartz is a dedicated medical doctor who adds insight to his screenwriting.
How impressive that is I can't say.
We find Susan Hart of Hart Literary Management as
a contest judge in 2002.
We find someone represented by Hart with
an option in 2001.
What I haven't found:
Haven't found an agency website.
Haven't found a list of produced screenplays.
