F.5. Good-Practice Recommendations
In addition to the requirements of this license, it is
requested from and strongly recommended of redistributors
that:
If you are distributing Open Publication works on
hardcopy or CD-ROM, you provide email notification to the
authors of your intent to redistribute at least thirty days
before your manuscript or media freeze, to give the authors
time to provide updated documents. This notification should
describe modifications, if any, made to the document.
All substantive modifications (including deletions) be
either clearly marked up in the document or else described in
an attachment to the document.
Finally, while it is not mandatory under this license,
it is considered good form to offer a free copy of any
hardcopy and CD-ROM expression of an Open
Publication-licensed work to its author(s).
