Guides: Technical standards: Standards available at Leddy Library

Most of the technical standards in our collection are available electronically, with only a small number of print copies. Historical print standards are also held, but they are often of limited practical use as they are superseded by more contemporary versions.

Search approach

Some standards, especially those from the IEEE, can be found at the title-level in Omni (the library's catalogue), but this is not always reliable as technical standards do not have the best title-level cataloguing metadata.

First, try searching Omni for the technical standard by title or standard designation.
Second, identify the issuing standards developing organization (SDO), and search by SDO package below

For assistance in searching for standards, please don't hesitate to contact us for research help.

Standards packages available in our collection

The Leddy Library licenses some comprehensive packages of technical standards from SDOs, which are listed below. However, packages are often cost-prohibitive, so we don't have packages from all SDOs. In these cases, we license technical standards on an ad-hoc basis (see bottom section of this page).

ASTM Compass
Access to over 13,000 active ASTM (American Society for Testing and Materials) standards along with historical and redlined versions. Search by standard title or designation.

IEEE Xplore
Access over 4,600 active and historical standards from the Institute of Electrical and Electronics Engineers (IEEE), including key technology fields, draft standards, and redlined versions showing changes. Either browse standards, or search by title or designation.

Expanded access pilot program

Leddy Library is joining a national pilot with ASTM to expand access to technical standards from other SDOs via ASTM Compass. The pilot includes UNE-adopted standards from ISO, EN, and IEC, and runs from September 15, 2025, to September 15, 2026, followed by an evaluation.

ISO Standards (via ASTM Compass)

Access all ISO standards adopted by the Spanish Association for Standardization (UNE) through the ASTM Compass platform. You can search by title or designation. Access is available as part of a one-year pilot starting September 2025.
EN standards (via ASTM Compass)

Access all European Norms standards adopted by the Spanish Association for Standardization (UNE) through the ASTM Compass platform. You can search by title or designation. Access is available as part of a one-year pilot starting September 2025.
IEC standards (via ASTM Compass)

Access all IEC (International Electrotechnical Commission) standards adopted by the Spanish Association for Standardization (UNE) through the ASTM Compass platform. You can search by title or designation. Access is available as part of a one-year pilot starting September 2025.

Ad-hoc standards licensed by the library

The Leddy Library licenses individual standards not available in the above packages on an ad-hoc basis. These standards are accessible on Nimonik.
