true; & i've been scouring archives holding issues of "archaeologia" 
published in the 1770s, but...
we now have much more detailed information (3D laser scanning technology, 
for example) that we're able & expected to do a lot more with
just basic documentation doesn't cut it when you want to do powerpoints, 
websites, regression & correlation analysis, serious datamining, etc.
& who has access to all the gray literature anyway? or can afford to 
publish/buy everything as a monograph with comprehensive appendices?
