ASTM Digital Library
The ASTM Digital Library is the historical archive of ASTM-published books, technical papers, manuals, monographs, journals, and Selected Technical Papers (STPs) dating back to 1932. The library aggregates 1,500+ books and 47,000+ articles and is accessed through ASTM Compass or direct subscription. Integration uses the same identity surfaces as Compass; no programmatic search API is documented publicly.
