Just to add in the controversy, with a somewhat related issue: Current crystallographic ethic presumes that a structure is deposited just before the submission of the paper. In a survey we did, we found that while in one journal only 2% of structures are deposited after the paper submission date, on another thats 5%, on another one that is 29% and in yet another one close to 50%.
The journals are Nature, Science, ActaD and Proteins in order of decreasing IF. Is there any correlation? To get some guesses first, Robbie can send the answer tomorrow at around noon (as I will be unavailable travelling ...)
