Hello,

if someone put his work under LPPL and also specifies the revision,
e.g.:

  %% pig.dtx
  %% Copyright 2005 M. Y. Name
  %
  % This work may be distributed and/or modified under the
  % conditions of the LaTeX Project Public License, either version 1.3b
  % of this license or (at your option) any later version.
  % The latest version of this license is in
  %   http://www.latex-project.org/lppl.txt
  % and version 1.3b or later is part of all distributions of LaTeX
  % version 2006/01/07 or later.
  %
  % This work has the LPPL maintenance status `maintained'.
  % 
  % The Current Maintainer of this work is M. Y. Name.
  %
  % This work consists of the files pig.dtx and pig.ins
  % and the derived file pig.sty.

Then this is correct for 2007, but after 1.3c has been introduced,
lppl.txt is now 1.3c, not 1.3b. And the LaTeX distributions
don't include 1.3a and 1.3b anymore. It's available as
  http://www.latex-project/lppl/lppl-1-3b.txt (or html, ...),
but these links are not part of http://www.latex-project.org/lppl/.

Would it be possible to put older revisions to the LaTeX distribution
and add these links to http://www.latex-project.org/lppl/?
Otherwise there are many work that refers to a license that is not
officially available.

Also if the license notice doesn't add a revision number
the problem remains:

  %% pig.dtx
  %% Copyright 2005 M. Y. Name
  %
  % This work may be distributed and/or modified under the
  % conditions of the LaTeX Project Public License, either version 1.3
  % of this license or (at your option) any later version.
  % The latest version of this license is in
  %   http://www.latex-project.org/lppl.txt
  % and version 1.3 or later is part of all distributions of LaTeX
  % version 2005/12/01 or later.

The latest sentence is wrong, because 1.3a, 1.3b are not part
of these LaTeX distributions and the user doesn't have the option
to choose these licenses.

Yours sincerely
