what do the historians write about these day

Answer:
I THINK...................
Historians use contemporary sources to write history... Having said that, at the time of events much can remain unknown... And writing history is much more then just tabulating events and consequences...
Writing history, IMHO, has more to do with the "how" and "why" then the "what"... The "what" can be found in contemporary media... Written, audio and visual... To determine the "how" and "why" access to official archives (minutes of meetings for example) is required... And more often then not, these archives are made available only many years, decades sometimes, after the fact...
Take for example the now widely known fact that any history of WWII would be highly incomplete without knowledge of Ultra which allowed the Allieds to read the most secret Axis communications sent with the Enigma machine. Communications which the Axis believed to be inviolate.
However, Ultra wasn't revealed until the mid 70's... 30 years after WWII ended... And, indeed, the revelation cause the rewriting of history as it had been known until then...
