Copyright is a problem especially on the Internet, and various attempts to establish once and for all the "fair use" of academic material have failed. Nevertheless, this lack of control does not justify the illicit copying and reproduction of writings.

We want to publish first, both on the Internet and hard copy format, unpublished and original materials; we ask authors who want to republish their papers to ask for our written permission; we require them to give bibliographic information on our journals in the first footnote and in the introduction; we give authors free written permission to republish their contributions only when they have agreed to our requests in writing.

We changed our Copyright Notice three times. Our current Copyright Notice reads:

All rights reserved under International and Pan-American Copyright Conventions. No part of this publication may be reproduced in any form or by any means, electronic or mechanical, including printing, photocopying and displaying, without the written permission of the publisher.
