Library Stackroom Loads in 1956 1

[WDM]

Does anyone know what the live loading would have been on a 1956 library floor in the Southeast USA?
The oldest code I have access to (mid 1980's)indicates 125 psf. I am analizing this existing waffle slab for new compact shelving loads of 200 psf. Thanks

1967 National Building Code lists stack rooms at 150 psf...reading rooms at 60 psf and corridors of libraries at 100 psf.

1947 AISC Steel manual - Library loads not listed.

ANSI A58.1-1955 (the standard that preceeded the ASCE 7 documents - lists library stack rooms at 150 psf and Reading rooms at 60 psf.
