If you go to their website, it looks pretty threadbare. I don’t know where the budget will come from to purchase the standards once for pdf-ization. I am personally interested in ASTM mechanical standards. ASTM has a reading room where you promise not to print. But the ASTM reading room does not have a search capability limited to itself. ASTM searches revert to mostly (or all?) for-sale publications. This makes the reading room almost useless.
