Thanks to everyone for your responses about a possible new format for
the notice of copyright that must include date and holder of
copyright.

Some opinions:

Instead of stamping with the ALA wording "Notice: this work may be
protected by copyright", attach the copyright notice that is
on the work itself - that may be on the first page of an article,
inside the front or back cover of the journal, or (for book chapters)
on the verso of a book's title page.  If no copyright statement is
found, then use the ALA stamp.

If the copyright information is on the first page of the article,
some are highlighting that and not bothering to stamp.

This article was recommended for a brief summary: "Digital Millennium
Copyright Act: A Mixed Bag" by Laura Gasaway, in the March 1999 issue
of Information Outlook (p. 14 & 16).

Finally, there was some disagreement about the need to change to a
new format and the belief that the old ALA statement still works.
