This depends on your camera. If the camera's internal format is JPG, the 
only thing that TIFF file does for you is take up a lot more space. If you 
can save RAW files (straight off the sensor, and not processed by the 
camera's internal software) you may be getting 12-bit images rather than 
8-bit ones (RAW=12, TIFF=8). Read the camera's manual to find out.

That said, JPG is a lossy compression format (meaning it throws away data 
during the compression process) and TIFF isn't. When you convert a file to 
JPG, you are technically losing fidelity, which is probaly what the 
librarians are all adamant about. I'm sure the librarians would recommend 
reading the manual, though.
