Hi Bob
Non whatsoever. But that may change this year! <G>

I just did the following: Opened a TIFF saved from a RAW file. Made a copy
and saved it as a full quality JPEG (equivalent of sending a JPEG to an
library). Closed it, opened it and then saved it as a copy (equivalent of
them converting from a TIFF). Closed it and opened both JPEGs and dragged
them into the TIFF's window. Turned the layers on and off of the two JPEGs
and can see absolutely no difference at 100% between the two JPEGs or when
either one is compared to the TIFF layer.
As for resizing JPEGs, I don't think it makes any "noticeable" difference
whether you resize downwards, as an agency would do, I assume, from a TIFF
or a full quality JPEG from a TIFF or from the copied, full quality JPEG. If
they're going to make hundreds of copies, as long as they do it from the
original submitted JPEG, they should all contain the same un-noticeable
difference. If they make a copy and then a copy of that and then a copy of
that...well...
If you submit a full quality JPEG, there is absolutely nothing to stop the
library/agency from converting it to a TIFF. When I was doing graphic design
work, I used to receive full quality JPEGs on CDs. I would save them to my
HDD as TIFFs, work on them as needed, save them as TIFFs to submit with the
page layout file. I haven't worked in a graphic hot house but I suspect the
above practice is quite common.

I think keeping drum scans is slightly different to keeping digital files.
<G> One assumes you are keeping only your best whereas Andy says he is
submitting 1000's!! His exclamations...
Nuff said.
