I sort the publications I post on The Astrochymist by the month in which they are formally published in a journal issue. Sometimes articles end up in limbo for an extended time. This is a particular problem with what I call "special issue limbo." While it is common now to have article collections that are spread out over multiple issues of a journal, some journals still accumulate articles until the issue is closed and published.

From time to time I search more broadly than my usual slate of 50+ journals where most astrochemistry articles are published. The Limbo page is a good place to cite articles in press in journals like JACS, J Phys Chem C, etc. so they will make it onto the main Publications page in due course.
