Thanks for the info.
This has happened before, eg https://debbugs.gnu.org/29671
The simplest solution is if the FSF store keeps
https://shop.fsf.org/product/emacs-manual/
working as a redirect to wherever the current manual is (or a short note
saying that it is out of print when applicable).

I will ask sales <at> fsf to do that, unless you know a better address?

Hello Glenn,

This seems like the best thing to do. Thanks for your prompt reply.

Can we maintain a list of redirections ourselves using a .htaccess file?
Do you know if the file will be read by the web server?

I was actually about to suggest something easier: point the readers to
an address that will never change, such as this:

   https://shop.fsf.org/collection/books-docs

Of course, if we can arrange for a more focused URL that won't be
invalidated by bitrot, that would be better.  However, I do suggest to
at least consider the "easy" solution against the risk of a 404 with
the more smart one.

We can't ourselves do that for the shop.fsf.org domain, no.

> Do you know if the file will be read by the web server?

.htaccess works and is used eg in emacs/manual/.

Are you sure about "never"? :)

Emacs can change to any URL for the future, but the old URL is used in
past releases and their announcements, so it would be simplest if it
comes back. It ought to be trivial for the FSF store to set up a
redirect. I will do that today.

I meant to say that I will ask them to do that.

Hello all, 

I quite agree with Eli. A generic redirection would be better.

If you want to keep the link as it is, I don't think a .htaccess
redirection on the gnu.org server would work, because the link points
to shop.fsf.org. You would have to ask the FSF sysadmins
<sysadmin.fsf.org> to update the redirection that seems to exist
already, or replace it with a generic one; something like:
  Redirect http://shop.fsf.org/product/emacs-manual/ https://shop.fsf.org/collection/books-docs/
The visitor would easily find the current Emacs Manual.

If you don't want to wait for the FSF admins to do this, I'm afraid
you will have to change the links in the Emacs home page and manuals.
At least, you can use a generic link that will not rot:

* The simplest URL is "/order/". It is rewritten by the gnu.org
  server:
    RewriteRule ^/order/.* http://shop.fsf.org/ [R]
  The visitor would land on the main page of the FSF shop, and follow
  the menu link to the books-docs section.

* You could also use an address in the emacs directory (say,
  /software/emacs/printed-emacs-manual.html), and redirect to the
  current version of the printed manual. This can be done in
  .htaccess, or in a page called "printed-emacs-manual.html".
  You would still have to update the redirection whenever the
  printed version changes, but this isn't going to happen any time
  soon because they just released the 18th edition.

* A variant of the previous method is to use the .symlinks file (no
  real page needed).

My 2 cents.

Best regards,
Thérèse

Oh, maybe you meant in future use eg gnu.org/s/emacs/manual/printed, and
have that redirect wherever. Sure, just add whatever you want to the
.htaccess file.

Hello,

A wrong link to the printed manual is also found in
/software/emacs/documentation.html. This one can be fixed right away
(diff attached).

sales <at> fsf have fixed the https://shop.fsf.org/product/emacs-manual link.

(I did ask if they wanted Emacs to use a different link in future, but
they did not comment.)
