Leo Jolley: a short appreciation

Using his Information Scientist pseudonym of Icarus, Alan Gilchrist once called the Aslib Co‐ordinate Indexing Group (CIG) (now Aslib Informatics Group) a bunch of free‐thinkers—the hippy fringe of the information profession. As the leading light of this Group (Leo Jolley was its Chairman from its formal inception in 1970 until his death on Christmas Day 1976) one might have expected him to epitomize these alleged qualities, but this was not so. Leo was neither long‐haired, figuratively or otherwise, nor was he a particularly free‐thinker. His work relating to information retrieval tended to be highly formalized: for a time he was unjusdy criticized for his attempt to rigorously define the fundamental nature of feature card systems. Later he had to suffer similar criticism from the present writer when he attempted to define and standardize the vocabulary relating to co‐ordinate indexing and thesaurus construction. Leo was a highly individual thinker, however, and he certainly existed at the fringe of the information profession. His contacts with the profession appear to have been limited to the CIG and to the Classification Research Group. He was neither a member of the Institute of Information Scientists nor of the Library Association, and was affronted if accused of being a librarian. Thus, he formed a part of that limited band who have contributed much to the profession without really being a part of it. This must be qualified, however, in that he had established a company (J. L. Jolley and Partners) which operated a range of services from consultancy to punching holes in feature cards.
