One of your prime responsibilities as an
author is to ensure that all material you
supply is your own, or, if it is taken from
another source, that it is clear of legal
difficulties for reprinting. Keep in mind
that a manuscript with outstanding permissions
cannot be considered ready for publication.
Once you have determined which items require
permission, you should organize your material
and apply for permissions as soon as possible
according to the procedures outlined in our
and Permissions Quick Guide (238Kb, PDF).
