Index to abstracts and references

One of the few outstanding and comprehensive guides to the technical literature is Abstracts and References, which has been reprinted monthly in the PROCEEDINGS since June, 1946 from Wireless Engineer in England. This material is compiled from over 200 leading journals by the Department of Scientific and Industrial Research in London for Wireless Engineer. Its appearance in PROCEEDINGS has provided readers with an extremely valuable digest of a major portion of the significant contributions to the technical literature. As valuable as this service has been, its usefulness has been only transitory. The abstracts can be read to great advantage as each issue appears, but once read, their usefulness ceases. There is no ready way of referring back to them at a later date and finding specific information. Thus, a glittering treasure of 30,000 abstracts now lies buried on the bookshelf, beyond the reach of the average reader. In order that the 3,700 abstracts published last year may be of permanent reference value in the future, an annual index has been reprinted from the March, 1955 issue of Wireless Engineer and is published as Part II of this issue of PROCEEDINGS. The index, which is separately bound, has been mailed together with the regular issue (Part I) to all IRE members and subscribers. Since the abstracts are reprinted in PROCEEDINGS one month after thev appear in Wireless Engineer, the index covers those abstracts which were published in the February, 1954 through January, 1955 issues of PROCEEDINGS.
