Organic Electronic Spectral Data: v. 26

In 1965 a co-operative effort to abstract and publish in formula order all the ultraviolet-visible spectra of organic compounds presented in the journal literature was organized through the enterprise and leadership of M.J.Kamlet and X.E.Ungnade. "Organic Electronic Spectral Data" was incorporated in 1957 to create a formal structure for the venture, and coverage of the literature from 1946 onward was then carried out by chemists with special interests in spectrophotometry through a page-by-page search of the major chemical journals. After the first two volumes were produced, (covering the literature from 1946 through 1955), a regular schedule of one volume for each subsequent period of two years was inaugurated. Altogether more than 50 chemists have searched a group of journals totalling more than one hundred titles during the course of this sustained project. Additions and subtractions from both the lists of contributors and of journals have occurred from time to time.
