Hmm, here's a question I hadn't considered. What happens when an online-only journal quits publishing and (apparently) deletes its archives? That's what seems to have happened with the "Journal of Advances in Developmental Research".
Now, to a first approximation, the loss of many of the papers in this journal will not, in all likelihood, be much of a setback. Here is (was?) its stated focus:
The Journal of Advances in Developmental Research is a peer-reviewed multidisciplinary journal that publishes research articles, general articles, research communications, review article and abstracts of theses from the fields of science, social sciences, sports science, humanities, medical, education, engineering, technology, biotechnology, home science, computer, history, arts and other fields which participates in overall development of society.
It provides a platform to discuss current and future trends of research and their role in development of society.
Now, that doesn't sound like anything anyone would want to read. But as long as your check cleared, you could publish in it - it was one of those bottom-of-the-barrel predatory publishing venues. What happens now, though? If there was something worthwhile in any of those papers, we'll never have any way of knowing, because they're all gone. Can (or should) the authors resubmit the papers somewhere else where they can be seen?
Here, for reference are Jeffrey Beall's current criteria for a predatory publisher. One of them is that they "(Have) no policies or practices for digital preservation". Although these guys seem to have had a policy, if you count "wipe the hard drive" as a policy.
