          The IHSDM Library includes all recently published materials on IHSDM in online and/or hard copy format. Past published materials, denoted as archive, are also available; these materials are somewhat dated, but may still contain information of interest to serious researchers. Some publications are available only for purchase from the National Technical Information Service (NTIS).

**Please Note:**

Many of the online documents are in Adobe Portable Document (PDF) File format, which requires a free Adobe Acrobat Reader.
