Science Citation Index 1961 and Science Citation Index 1964

摘要

In today's age of man-made wonders, superlatives such as "stupendous" and "colossal" have ceased to have the meaning and the impact which they evoked some years ago. Nevertheless, it is to such a word that one turns for an overall description of the Science Citation Index; it must be regarded as a monumental undertaking and achievement. Works such as this do not spring full blown from the head of Zeus, and the many years of research, experimentation, and refinement which have gone into this production may be traced through the professional literature. The work itself must be examined in two pieces, as indicated above, because the projected changes in the 1964 Index warrant special consideration.
