A FEW WORDS OF EXPLANATION: The alphabetical listing shows all Sherlockian societies now in the computer file, sorted alphabetically by society name. The first line of the listing shows the full name of the society. The second line of the listing shows three items of information: Active: can be yes (Y) or no (N) or provisional ( ). Societies are listed as active only if they have responded to a questionnaire. Societies are listed as inactive from the listing in the December 1983 issue of the BSJ, from other sources, and from information supplied by the contacts. Societies are also listed as inactive if the contacts did not respond to questionnaires within one month (the inference being that an active society answers its mail). Societies are listed as provisional during the one-month waiting period. Category: can be geographical (G), professional (P), or other (O). Categories are assigned only to active societies, from information supplied by the contact. Contact: the name of the contact for the society. The listing of geographical societies shows all active geographical societies, sorted by geography. The full name of the society is followed by the geographical code (country, state or province, and city), and the name and mailing address of the contact. The listings of professional and other societies use the same format as the listing of geographical societies, except that the societies have been sorted alphabetically by full name.
