Removing bookplate

I have a problem book and I wondered if you might have some ideas.
Here's the scoop: The book is Final adventures of Sherlock Holmes,
by Sir Arthur Conan Doyle, New York: For the Members of The Limited
Editions Club, 1952.

This book belongs to an institution and resides in their special
collections, and someone missed their aim when they applied a
pressure sensitive bookplate.  The bookplate landed on the upper
portion of the contents page.  Thank goodness the release paper had
only partially been removed.  I don't know when this occurred,
therefore I do not know how long the book plate has been adhered.
Now the university would like this book plate removed, and the text
attached to the adhesive part of the bookplate reattached to the
page.  I have tested the adhesive on scraps of the bookplate and
found that ethanol and isopropyl alcohol seem to remove the
adhesive, at least soften it a bit so it rolls off.    Most
unfortunately, both solvents solubilize the ink in the text.  So I
do not want to saturate the  portion of text covered with the
bookplate as I don't want the ink to solubilize and run all over.
I'm hesitant to try any solvent which are less polar when these
polar solvents solubilize the ink.   Any ideas or suggestions?
