Indeed, this is just one instance of a general oversight in the 
Documentation Center -- neglecting to say explicitly that you must load 
the package in which a function identified as being from a package is 

Thus if you go to the Histogram reference page, at the top you'll see in 
gray, "HISTOGRAMS PACKAGE SYMBOL", but nowhere on the page does it show 
the expression to load the package.  And that gray legend at the top is 
easy to miss.

Moreover, if you follow the "More about" link at the bottom of the page 
to go to the Histograms Package page, you'll just find a list of the 
packages two functions (along with some further "More about" links), but 
still nothing about loading the package!

In Mathematica 5.2, the page for a package typically showed near its 
start the expression needed to load it.  (In the case of function 
Histogram, this was the Help Browser page on Graphics`Graphics`.)
