Are you referring to the HTML title, which appears between the
<title></title> tags? Or are you referring to the title  that is
displayed in the bar just below the SharePoint menu?

If you are referring to the latter, from the Web Part Page, select
Modify Shared Page >> Modify Shared Web Parts >> Web Part Page Title
Bar.

I am referring to the HTML tags.

I know I can change  the title  in the template  .aspx pages, but then I
would have to go back and recreate each page. I would also not be able
to assign each web  part page  a unique  title (unless I edited the
template each time I created  a document, which I'm not going to do).

One possible solution:

msdn.microsoft.com/.../...ngcustomwpptemplates.asp

Those are the same instructions I followed. Here's the problem  with
that:

Say you have created  a custom site definition, SPSCLIENTS. Inside of
this, you create a custom client template  spstd9.aspx. Everytime you
create a new client (using spstd9.aspx), the <TITLE> tags remain
constant. So now every page  is titled the same.

I know I can edit  the title web  part, but the HTML title  tags cannot
be changed. I have 200 clients, and cannot create 200 spstd*.aspx
pages.

The article you are referring to does not address this issue, or I am
missing it?

Use the same token inside the <TITLE> tag that is used in the title  bar web  part.

(Sorry that I didn't put this in the original message. The brain was moving faster than the fingers.)
