Indeed: it works! Thank you for this code.
This is the first part of the job: in fact, I don't want to copy the reference as they appear but I use a dictionnary to put complete reference in the footnotes; this is not complicated, but the thing is that I must format the reference inside the footnote...
I've started to work on that, but before continuing, I am going to keep on looking for the portion of code that doesn't work, in order to understant better VBA, and to study the .Find method.
If anyone can help for that, by providing sources, sites, books reference or answering questions...
In any case, I acknowledge participants for their help!
