Literature Review Abstracts and reviews collected bv the International Bureau of WIPO dur& a scanning of journals concerned with inf;rmation retrieval and patent information. 1. Alternative approach to conventional erasable optical disk substrate manufacturing in outical information svstems. G. Galic. dptical Information .?vstems ‘88. Conference oroceedines. Meckler. pp. 53-56. VIII+i96 pp. 19%. Erasable disk information-coding pits are comparatively lower resolution and ‘signal to noise’ ratio versus the molded-in pits of CD-ROM optical disks. This has implications for both drive and media, and most especially for the disk substrate, which must be of comparatively higher quality than conventional CD-ROM. A new, alternative technology for reducing the constrictiveness of optical disk molds comes out of the ophthalmic spectacle lens field, where it’s been successfully used over 2 years for molding polycarbonate RX spectacle lenses. This patent-pending approach provides lower optical stresses and birefringence by using different, gentler path to form thermoplastic molded disks. Preliminary data are presented on 130 mm polycarbonate disks molded thereby. 2. Twenty-five years of science citation index some experiences. R. L. M. Synge. J. Chem. Inf. Cornpat. Sci. (USA). Vol. 30, No. 1. pp. 33-35. Feb. 1990. Science citation index (SCI) depends for intellectual content entirelv on citations by authors, who are someGmes prodded by editors and referees. Its patchiness is therefore not surprising, but frequently it gives access to relevant and up-todate documents not easilv accessible bv other means. Two contrasting ‘citation families’ are described. The first familv. dealing with the various ascorbic acid derivatives having C substitution at C-2. actually retrieved very nearly all the relevant documents (other than patent s ecifications) that were retrieved bv a 0 AS Online substructure search. Ore&ic chemists are clearly careful authors_Thc second family. dealing with amino acid residues covalently bound in soil organic matter, yielded documents having surprisingly little overlap with those retrieved bv using a carefully devised boolean ‘profile’
on the general subject index of chemical abstracts. This was only partly because SC1 is beset bv language-barrier uroblems to which che’micai a&tracts is ‘immune. The SC1 management might extend its journal coverage. but otherwise improvement can only come from a more serious attitude to piacing references in primary Dublications. SCI remains a comulement io. not a substitute for. other daiabases. 3. The use of Dialog 2 in the information system physics. U. Wellhausen. lnformatik (East Germany). Vol. 36. No. 5, pp. 163-166. 1989. Dialog 2 is a multi-user system. online or stack oDerating. developed for bibliographical ahd patent search in the field of Dhvsics. Enelish is its access language. It c’an’be expa;ded by combining it with other programs to create a major international science and technical information system. The data can be formatted or unformatted. The way Dialog 2 is built and used as a central physics information centre in East Germany is described in detail. 1. Managing image databases: A European community perspective. F. A. Mastroddi. lnf. Media Technol. (UK), Vol. 23. No. 2, pp. 60-73, March 1090. The commission of the European Communities’ Docmix study on image banks in Europe has indicated clearly that imagery technisues have acted as catalysts to opening new ireas of activity in orofessional life. The future ootential of ele’ctronic imagery is very broah especially in the communications-oriented industries. After looking at optical storage media the paper goes on to discuss image bank management, including image collection. image bank management systems. image retrieval, standards for image formats; future prospects; and new pil&/demo projects. The latter includes image banks. oatent information, intelligent izterfaces, tourism information, and standards information. 5. Online patent searching: guided by an expert system in online. S. B. Ardis. Online (USA). Vol. 14. No. 2. DD. 56-62. March 1990. ‘The Patent Inforkition Assistant was designed to assist students, faculty and the general public with patent searching. The author gives an overview of the menu based program. She looks at the telecommunications module, program paths, output printing, costs, typical operation and the future. The system has been well received by patrons. 6. CASSIS/CD-ROM: makes patent searching easier. K. Jackson. Laserdisk Pro/: (USA), Vol. 3. No. 2, pp. 60-66, March 1990. Manual searching for patents is a frustrating and slow process. Several

good online systems exist. one of which is the CASSIS/CD-ROM (Classification And Search Support Information System on CD-ROM). Available from the U.S. Patent and Trademark Office, the system is supplied with CD-answer retrieval software. The article outlines the equipment required for CASSIS. the searching of CASSIS files and of the manual of classification, and its printing and downloading capabilities. 7. Advantages of online databanks. M. Lipp. Etz (West Germar7v). Vol. I IO. No. 23-24. pp. 125X-1260, Dec. IYXY. The author briefly describes the different types of online databanks. the various data transmission services of the Fcdcral German Post Office. and database search and retrieval techniques. The questions and answers of a specific search of patent and market information databanks arc shown as an example. 8. A Chemical Abstracts training seminar for science librarians. B. Slu&kv. Sci. Tech&. Libr. (USA). Vol. IO. ‘No. I. pp. 55-76. Fall lYXY.‘Science librarians at the New York public library without a strong educational background in chemist,ry often had difficulty in searching the prmted chemical abstracts. A I-hr seminar was held to teach the fundamentals 01 Chemical Abstracts with an emphasis on finding references to well known chemical substances. Uses of the index guide. author index. chemical formula index. patent index. and index of ring systems were shown. A brief discussion of online searching of chemical abstracts followed.

Bibliometrics is the quantitative study of literatures as they are reflected in bibliographies. Its tasks is to provide evolutionary models of science. technology and scholarships. Distinctively, it construes these worlds as realized over time through publications - more exactIv. through their biblioeraDhic records. ?‘he chapter reflects eve; a decade of development within bibliometrics, choices being drawn from the period 1977-1988. Focus is upon the salient lines of research within the major specialities such as co-citation studies, given little coverage elsewhere. Bibliometric patent analysis and mathematical modelling of library circulation are outlined.
