Why conference chair asks for accepted papers sources? I got my paper accepted to a conference, whose proceedings will be published in IEEE digital library (Xplore). The General chair asked me for the paper source, I was astonished when she insisted on me submitting a Word version even though the conference offered LaTeX template which I used.
My question is twofold:
Why would the conference chair need the source of my paper?
Knowing that I couldn't convert my pdf paper to a decent Word file,
is it my problem at all to do that since the conference allowed using a
LaTex template for paper writing but did not alert that a Word source would be required in case of acceptance?
While we obviously do not know the Chair's intent (unless she happens to be a stack exchange poster), the most likely situation to me is that there's some sort of formatting related issue (or possibly some typos, etc. that need correcting) in your submitted version that they are incapable of fixing given your PDF file.

This does not necessarily imply it's your fault - typesetting systems are sometimes fussy, but asking for both a Word version and the source indicates, to me, that they want "A version they can edit".&nbsp;&nbsp;&nbsp;

On a practical level, yes, it's your problem. You could refuse of course, with unknown results.
