[R] NEWBIE: @BOOK help?

[Zembower, Kevin]

In Henric's recent post, he included this output:

@BOOK{R:Harrell:2001,
  AUTHOR = {Frank E. Harrell},
  TITLE = {Regression Modeling Strategies, with Applications to
                  Linear Models, Survival Analysis and Logistic
                  Regression},
  PUBLISHER = {Springer},
  YEAR = 2001,
  NOTE = {ISBN 0-387-95232-2},
  URL = {http://biostat.mc.vanderbilt.edu/twiki/bin/view/Main/RmS}
}

Can someone tell me how this is generated? I've noticed this in a few
recent posts. I attempted:

RSiteSearch("@BOOK")
?BOOK
?book

but it didn't return anything useful.

Thanks.
