Science & Technical Reports: Frequently Asked Questions

The American Documentation Institute (ADI) collection was transferred to the Library of Congress' Photoduplication Service (now called Duplication Services) in 1953 and found a permanent home in the Technical Reports and Standards Unit in 2009.  Requests for an ADI deposit are made at the Reference Desk in the Library's Science and Business Reading Room, 5th floor, Adams Building or via the Science and Technical Reports Ask a Librarian Service . To purchase a copy of an ADI please contact the Library's Duplication Services. 

The Library's ADI deposits run through June 1968 and are available in paper or microformat. Of the 10,000 hard copy and microform documents in the ADI collection there are some gaps in the early numbers (50-300) and the oversized deposits have been pulled for conservation. 

In 1968 the ADI became the American Society for Information Science (ASIS) - at which point it ceased using the ADI classification. In that same year, ASIS announced that future publications would be available through the National Auxiliary Publications Service (NAPS) from the Microfiche Publication Division of Microfiche System Corporation. The Library does not have holdings of the NAPS deposits  ASIS later changed to the American Society for Information Science and Technology and in 2013 became the Association for Information Science and Technology (ASIS&T).
