Yes.  That is what the argument 'lib.loc' to library() and other functions 
refers to.

A 'library' is a collection of packages stored in one directory.

library("pkg") means `go to one or more libraries, find package pkg and 
load it up'

In S parlance what in R is a `package' is a `library section' or 
(latterly) also `chapter'.

In English usage a library is a collection of volumes, not of recipes or 
stories or articles.
