<p class="MsoNormal">We have experienced the same thing with T&F and with University of Chicago Press Journals over the last week. U of Chicago Press thinks the issue is on their end, but we and they are still trying to establish exactly the source of the issue.
In the past, we’ve seen citation software causing this same issue but at least in the T&F case (where we talked with the user), that was not the case this time around.<u></u><u></u></p>
