Abstracting Journals and Information Retrieval

Original papers are abstracted relatively soon after publication, and these summaries, which are often no more than the author s own abstracts which normally precede the main text of a paper, are published in the various abstracting journals. The most comprehensive and important of these is 

Other major national publications of this type are the German Chemisches Zentralblatt, and the Russian Referativnyi Zhumal, Khimiya. 

The only abstract journal concerned solely with the field of organometallic chemistry is Organometallic Compounds (Dl), which covers patents and some of the chemical literature. About 5000 abstracts were published in 1969, relating to all aspects of Main Group and Transition element organometallic chemistry. Sections on olefin polymerization, polymerization catalysts, additives for plastics, paints, fuels, and lubricants, and related topics, follow a large section on organometallic chemistry.

More recently, the explosion in volume of chemical publications, and the large increase in amounts of data which result, have led to the development of computer-based systems for processing, correlating, and retrieving the information. Many services of this type are available to the chemist, and they include various personalized services devoted to making rapid but useful literature surveys. Many obstacles remain to be overcome before systems will become available which will not produce a large amount of irrelevant information in addition to required items. One approach to the
