Where can I find directives, instructions, standards and specifications?

Looking for Mil specs or Standards, or other standards of interest to NPS researchers such as ANSI, ASTM, NIST and others? You'll also find links to sources for Presidential documents, Federal and uniformed services, selected NATO standards and much more! 

If you are an NPS student, faculty or staff member and need a standard that the Library does not have, request it using the Request Article or Book service.
