package MathWorld and path in mathematica; Get::noopen: Cannot open MathWorld

Get::noopen says that the file could not be opened, not that there was a problem with the code inside.

Is the MathWorld folder in one of the directories listed by evaluating $Path?
method of specifying the package is to provide the full path to it.
- Type in Mathematica:
Get[]

and

1.  place the cursor between the square brackets, 
2.  go to Insert menu, File Path, 
3.  in the directory dialog box that opens, trace down to the .m file and Open it (that puts the path into the Get),
4.  evaluate the Get that now has the file path.
