Is anyone using the 11th or 12th ed. text along with the e-text?

[Robert Zellmer]

Our official textbook is the 14th edition e-text.  However, people
often want a real paper edition and will use older editions of those.
When I put up the info for a quiz I have to go through each edition
to see what problems apply.  This is a rather tedious undertaking.
I would like to cut some of this process out if possible.  To that end,
I need to know if anyone is using an 11th or 12th paper edition, along
with the 14th ed e-text.
