I did try it just now with a library which I know is no longer needed
(although aptitude hasn't removed/purged it). This is on a Debian sid
machine.
$ aptitude search libgs?
p libgs-dev - interpreter
for the PostScript language and for PDF - Develop
v libgs-esp-dev -
i libgs8 - The
Ghostscript PostScript/PDF interpreter Library
i A libgs9 - interpreter
for the PostScript language and for PDF - Library
i A libgs9-common - interpreter
for the PostScript language and for PDF - common
Just extracted partial listing. It seems aptitude doesn't respect the
wildcard '?' as it produces a whole listing but that I guess is
another issue.
See libgs8 :-

Description: The Ghostscript PostScript/PDF interpreter Library
Ghostscript is used for PostScript/PDF preview and printing. Usually
as a back-end to a program such as ghostview, it
can display PostScript and PDF documents in an X11 environment.
This package provides the Ghostscript library which makes the
facilities of Ghostscript available to applications.

As can be seen both libraries seem to have the same function .
$ sudo aptitude remove libgs8
[sudo] password for shirish:
The following packages will be REMOVED:

Then I tried to see if any listing is/was possible :-
$ dpkg -L libgs8
Package `libgs8' does not contain any files (!)
$ sudo aptitude purge libgs8
The following packages will be REMOVED:

Purging configuration files for libgs8 ...

D000001: removal_bulk purge done, removing postrm
`/var/lib/dpkg/info/libgs8.postrm'
D000001: removal done
It seems there is/are configuration files which do get removed when
you purged but it seems those are either not known by dpkg or there is
some other way to find those out.
As said before as well, sorry for the noise :)
