From a JournaIism class I recall a distinction between timeless and current (IIRC) articles, whereby for example an article of timeless interest is scheduled, but then new news comes up that is time-sensitive and needs to be reported ASAP, so the timeless article can wait.
I find an analogous phenomenon in Academia. Some fields are more timeless; publications have a long tail and stand the test of time, whereas publications in fields responsive to rapid changes in technology or social trends have a much shorter shelf life.
In sharing my works as a cluster specialist this week, publications on Bilingualism, ancient Japan, and the Academic Life in historical perspective seem to make time stand still, compared to Online Education, which is sensitive to trends in educational technology.
