• CA adds annual formula index, first to be used in an abstract journal. These formula indexes did not indicate molecular structures, or functional groups, but served as very broad screens for searching purposes (Perry, Kent, & Berry, 1956).
• Herbert E. Soper (UK) receives US patent for subject based optical coincidence system for use in statistical recording (Thompson, 1961).

• IUPAC establishes commissions on chemical nomenclature to formulate rules for naming chemical compounds systematically (Perry, et al., 1956).
• Science Service, at the National Academy of Science in Washington, DC, is established to disseminate scientific information. Edward E. Slosson is the first director (Schultz & Garwig, 1969).
• CA publishes its first chemical formula index (Weisgerber, 1997).
• International Committee on Intellectual Cooperation, under auspices of the League of Nations, is established (Werdel & Adams, 1976).

• April: The Union of American Biological Societies is established with principal purpose of publishing a unified abstracting service for bio-sciences (Steere, 1976).

• French patent for use of subject based optical coincident system is issued to Bourgeaud and Liber. System incorporates some aspects of Boolean searching. This patent forms the basis of the J. Cordonnier system of aspect cards (Thompson, 1961).
• Eighth edition of Gmelin Handbuch der Anorganischen Chemie published, under sponsorship of Deutsche Chemische Gesellschaft.
• The Powers Accounting Machine Company introduces a tabulator with alphabetic capacity (Norberg, 1990).
• First use of a facsimile transmission between NY and Cleveland. Results are printed in The New York Times (Emard, 1976).
• November: Rockefeller Foundation makes grant of $350,000 to cover expenses for a ten year period for creation of Biological Abstracts. Rockefeller eventually contributes a total of $723,000 for the publication (Steere, 1976).

• By this time, the use of tabulating machines has achieved a conventional makeup that is to stay pretty much the same until the 1950’s: punch, tabulator, sorter, and, occasionally, a verifier, interpreter, and printing tabulator. Almost every large company has a "Hollerith" department by this time.
• Alfred Perkins (England) receives a US patent for his edge-notched card (previously patented in the UK; not sure of date). Earlier edge-notched cards are crude compared to his. This is the first generally applicable system. US rights to the patent are sold to the McBee Corporation in 1932 (Reichman, 1961).
• Paul Otlet (Belgium) and Robert Goldschmidt (Belgium) describe the advantages of a microphotographic library consisting of a portable cabinet and a pocket sized viewing device capable of holding as many as 18,759 books of 350 pages each (Buckland, 1996).
• Emmanuel Goldberg (Germany) demonstrates microfilm reduction potential by placing entire text of the Bible 50 times over on one square inch of film (Buckland, 1996).

• Carnegie Corporation funds the establishment of the Graduate Library School at the University of Chicago. Principal purpose of the school is to be research oriented and to operate a Ph.D. program in library science (Buckland, 1996).
• Watson Davis and Edward Slosson propose a method for disseminating information via a "miniaturephotographic" process. Davis (?) coins the term microfilm (according to Schultz & Garwig, 1969).
• British Chemical Abstracts begins. Becomes British Chemical and Physiological Abstracts in 1938 and British Abstracts in 1946.
• In the United States Biological Abstracts is first published (Steere, 1976).

• Emmanuel Goldberg (Germany) develops process for applying electronic signals to selection of data on microfilm. US patent is applied for in 1928 and is granted 29 December 1931. This development has significant influences on work of Vannevar Bush in early work on the Rapid Selector (Jahoda, 1961).
• Nippon Kagaku Soran, a Japanese chemical abstracts journal, is published.
• International Federation of Library Associatons (IFLA) is established. This is a direct descendant of the International Library and Bibliographic Committee, founded in 1926 (Werdel & Adams, 1976).
• The Powers Accounting Machine Company becomes Remington Rand.

• IBM, the old CTR, introduces the 80 column punched card.
