Consideration is first given to indexes compiled by or with the aid of machines, including citation indexes. Advantages, disadvantages, and possibilities for modification and improvement are discussed. Experiments in automatic assignment indexing are summarized. Related research efforts in such areas as automatic classification and categorization, computer use of thesauri, statistical association techniques, and linguistic data processing are described. A major question is that of evaluation, particularly in view of evidence of human inter-indexer inconsistency. It is concluded that indexes based on words extracted from text are practical for many purposes today.

- Craters From Four Equal Charges in a Horizontal Square Array
- Craters were observed resulting from square arrays of 64-pound charges at various spacings and depths. The closest spacings yielded craters very like those from single 256-pound charges, while wider spacings yielded craters more or less square in shape and with a mound or pier at the center. Generally, the areas so uncovered were greater than for single 256-pound charges, except for very deep charges. Volumes, too, were enhanced by this configuration by as much as a factor of three. If the same factor is maintained for nuclear charges, the cost per unit volume of a crater from such an array will be within 20 percent of that for a single charge.
- The Cumulus and Meteorological Events of the Florida Peninsula During a Particular Summertime Period: Cloud Refractive Index Studies IIIA
- The cumulus cloud events of the Florida peninsula that were observed during a 19-day period of photoreconnaissance in August and September 1957 are described and illustrated. The associated meteorological and rainfall events are also described and the intercorrelations among the various observations are pointed out. The study findings revealed that the principal factors governing the cloud and rainfall situations of the different days were (1) the low-level advection of water vapor into the peninsula from the oceanic surroundings, (2) the wind transport, into the heated peninsula from the oceans during the daytime, of pre -existing cumulus populations containing appreciable liquid water, (3) the low-level convergence, and associated updraft motion, engendered by the synoptic situation and the peninsula sea breezes, and (4) the precipitable water content of the lower Florida air mass.
