An incredibly valuable resource for mechanical engineering.
But the ASM Handbooks are not freely available, not even partially. The Digital Library is a paid subscription product.
What ASM does offer free is limited:
- Journals via Subscribe-to-Open (S2O) In 2025 ASM adopted a Subscribe-to-Open model for its 6 primary research journals, meaning articles are published open access if the journal’s sustainability target is met for the year. Octoparse These are research journal articles, not handbook reference data.
- Periodic free article promotions ASM occasionally opens free access to top downloaded articles from the previous year Apify — but these are time-limited windows, not a permanent free library.
- Advanced Materials & Processes magazine ASM’s trade magazine has some free articles at asminternational.org but it’s news/trends content, not engineering reference data.
