Many thanks for your replies. They were very helpful.

I or someone else here may be able to help you accomplish that. "

It is quite a complicated story! I was converting a very old and ragged pdf into Word using an OCR. The pdf had many footnotes listed at the bottom of virtually every page. The result actually was an excellent and very impressive scan. I then wanted to copy the whole document and put it as text without Word formatting into another program. All went fine until I realised that not all the footnote listings had been copied.

I will try other options, but if I get stuck I may well wish to take up your suggestion. At the moment I will not take this question any further. I am very grateful for your guidance so far.
