One thing that would help here is to set the vocabulary a bit more precise. We are talking about TWO different concepts of page-numbering here:

   print-page-number
   braille-page-number

A publication in Braille, in general, contains BOTH numbers. A braille reader should know all the time - in what print page - the particular content is located, because of reference resolving and other similar problems. A case frequently cited is of a teacher that says "lets open the book on page 75 ..." - the pagination in braille does not follow the pagination in print.

I have been demonstrated once the complexity of using an Index in a Braille scientific publication and it is rather substantial because once you are interest in a word, for example "manifold" you have literally to:

 - go to the TOC
 - locate the Index
 - go there and locate the word "manifold"
 - read the print-page-number
 - locate in the book the physical pages of that printed-page
- locate the definition of manifold - looking possible in more that one page

To place the "print-page-number" in the body of the text is simple and done all the time. One can basically place the print-page-number anywhere you need on the page - reserving a space for it on the bottom line, is just one of them.

To make a braille edition "know" know the print-page-number is much harder ... and possibly what Eitan was working on ...

Dear Professor Hammond,

Thank you for the detailed response.

Let me attempt to re-phrase my question in a simpler way.

The overall goal is to convert existing paged print documents to braille.
There are two aspects to this process. One aspect is translating the print
characters to the corresponding braille characters.  As a very simple
example, braille does not have separate small and capital letters so
titlecase words in the print source need to be preceded by a special braille
character that acts rather like a markup tag.  But the important point as
far as this discussion is that we can consider the translation aspect of the
process as a solved problem.

Braille is typically represented using a transliteration to ASCII characters so a document that has been translated to braille looks similar to a plain
text file.

The second aspect of the process of converting a print document to braille is to format the braille file by doing such things as indenting paragraphs,
centering headers, and paginating.

The problem which I apparently haven't explained clearly is that according to the pagination standards, braille documents do not have separate headers or footers. Page numbers are simply appended to the first and/or last lines of the ordinary (what I called body) text on each page. These lines must,
of course, be slightly shortened to accommodate the page numbers plus a
space or two to separate the text from the page number.

So my first question is whether one could use LaTeX to paginate an ordinary
plain text document (not necessarily braille) without using headers or
footers but rather with the correct page numbers included at the beginning
or end of the first and/or last lines of the text on each page?
