Couldn't they spend a little more time and write an expository background on papers? Certainly it would be the easiest part for an expert to write. I was reading several papers in the EE field the other day. Most of them all spend the first page restating the problem in practical terms and then have a substantial section reviewing the prior techniques. I found this darned helpful, especially since the primary material was often not online. Are they worried about wasting paper, or do they actually want to be uninviting?
