As chronicled in your researcher's journal as I researched my history of early lifestyles in South Asia...
I was a little
shocked with my librarian background (during grad school) while doing a bibliographic search
for additional sources I wanted to check, to see a list they probably didn't mean
to publicize of periodic publications to "discard on arrival" that
included interesting local archaeological and historical works.
Hopefully the publishers are keeping good archives...
