Mess with Emacs packages?

[Ignoramus16682]

I have iset up a new machine and found, to my upset, that a lot of
packages is missing. Examples are saveplace, for example. 


I want to know if there is a repository of installable packages
somewhere, such as repository of RPMs for Fedora core. I do see a list
of packages in my xemacs tools menu, byut it is embarrassingly short. 

Am I doing something wrong, or is there a site that provides a good
interface to getting a lot of packages.
