The ANSI standards are produced and/or approved and published by the American National Standards Institute. ANSI defines it's mission as:
"The Institute oversees the creation, promulgation and use of thousands of norms and guidelines that directly impact businesses in nearly every sector: from acoustical devices to construction equipment, from dairy and livestock production to energy distribution, and many more. ANSI is also actively engaged in accrediting programs that assess conformance to standards – including globally-recognized cross-sector programs such as the ISO 9000 (quality) and ISO 14000 (environmental) management systems"
Frequently ANSI standards are jointly produced with another organziation. An example would be the ANSI/IEEE 1149.6-2003 Standard for Boundary-Scan Testing of Advanced Digital Networks. If an ANSI standard is a joint standard with IEEE or ASTM, then the UMD Library will have electronic access to these standards (through IEEExPLORE or ASTM).
The UMD Library has a small selection of ANSI Standards in paper. To search for them, you can go to the UMD Library Catalog and then type in the the standard number, i.e. ANSI B152.2-1982 or the name of the standard (try both ways, if need be). If the library does not own the standard, you can request it through Interlibrary Loan.
