©Copyright 2002, 2003 by Bavarian Archive for Speech Signals, Ludwig-Maximilians-Universität München, Germany, D-80538 München, Geschwister-Scholl-Platz 1In addition to the ©symbol you should use the word `Copyright' or the phrase ``This corpus is the intellectual property of...''. Be sure to use the official (legal) name of your institution. For instance in the above example the ``Bavarian Archive...'' is not an official name; therefore we added the official name of the university where the BAS is located. If you share the copyrights (see below) then you should list all partners after the copyright. If you add or extend to your speech corpus later, add a new year to the copyright line.
To declare a copyright is one thing and anybody can do it. Another thing is to protect it against abuse. Consult your legal advisor about that.
