At least the feeling part is a question for Arash,
to whom I replied.

An Elisp "library" is a "package" with or without
any additional package-handling paraphernalia.

It can be a single Elisp file or a set of related
ones, e.g., files that are required or otherwise
expected to be used together.

When package.el and package repositories were
added to Emacs, the notion of Elisp package was
born.  A package is a library plus some metadata
needed or optional for the package-handling
apparatus.

E.g., `dired+.el' is a single-file library.
Files `bookmark+*.el' compose library Bookmark+.
Neither library is in a package repository (both
were in MELPA at one time).
