A lawyer I frequently practice with offers this tip. In trials with hundreds of exhibits, the jury will understandably have a difficult time sorting them out during deliberation and might even ignore them entirely. If you want to make sure they see the ones you consider most important, gather these into a stack and hold them up during your closing arguments. Tell the jury something like this: "Here are the the exhibit we think are the most important. I'm going to set them here on the rail. If you want to look at them later, ask for the stack of exhibits I set on the rail."
If you know the trial judge is going to send all the exhibits with the jury to the deliberation room, modify the procedure accordingly.
