Certain journals (for example, Optics Express) place the references of papers in between the abstract and the article text:
How common is this practice? Is there some specific design reason for this? As a casual reader, I find it disconcerting and annoying, and tend to see it as another barrier between googling the paper and actually getting at the text. However, I understand there may be other workflows for which this is useful. Can anyone point out possible justifications for this practice?
