It is quite probable that many members of this Society, particularly those with reasonably permanent headquarters, have started to collect geophysical data of some kind or other. If one keeps adding to such a collection over a period of years, the necessity arises sooner or later to classify this material in some way. The writer’s own collection, started some twenty‐two years ago, would be of little value to him or to anybody else unless it were arranged in systematic form. It is very annoying not to be able to produce a certain article or data although one remembers perfectly well having seen and filed it. Without an orderly classification system, much time is lost searching for it, and needless expense is often incurred in duplicating material already in the files.

Concept Hierarchies

The need to maintain classification and retrieval mechanisms that rely on concept hierarchies is as old as language itself. Familiar examples include the Dewey decimal classification system used in libraries and the system for classifying life forms developed in the 1700s by Carolus Linnaeus. A more recent example is Yahoo’s subject taxonomy.

AbstractThe Universal Decimal Classification system is widely used throughout the world for the arrangement of books in libraries and for the indexing of papers and reports as an aid to the retrieval of information. It is a comprehensive and language-independent system. The classification for astronomy and related topics (UDC 52) is used by many persons whose main interests are outside astronomy as well as by astronomical specialists. It is important that the classification be kept up to date, but the revision of UDC 52 is now overdue, as the last major revision was made in 1975 and published in 1977. It is clearly the responsibility of IAU Commission 5 to provide expert advice to the International Federation for Information and Documentation (FID) on the revision. Persons who are willing to participate in the work of revision are invited to write to the author, who is the current chairman of the relevant revision committee.

Library Collections

The Dewey Decimal Classification system, frequently used to arrange arts collections, has a number of commendable aspects but also some significant shortcomings. Evidence suggests that visual arts library users can further their creative ideas by browsing library shelves, and the author considers this should inform classification practice. Dewey, approached from a user perspective and applied with attention to the scheme’s potential, can provide a shelf order that promotes browsing. The common perception that Dewey is most suited to general library collections is perhaps not entirely justified. Within the visual arts, it possibly accommodates specialist resources rather better than is sometimes imagined, particularly with judicious adaptation. A number of modifications are easy enough to achieve and may be applied across a range of visual arts resources.

This Paper Presents a Classification System for Managing and Indexing Hardcopy Engineering Drawings, Referred to, in this Paper, as Drawings Library Management System (DLMS), Developed for an Appropriate Technology Research Centre in Botswana. the System Is Akin to Common Library Cataloguing and Classification Systems such as the Dewey Decimal Classification (DDC), Universal Decimal Classification and Others, which, though Are Well-Known and Have Been around for many Years, Are yet to Be Exploited for the Classification and Management of Paper Drawings. in Fact, Hardcopy Drawings Appear to Be Neglected Compared to the Softcopy Type, for which Various Scholarly Articles Have Been Done on their Classification, Retrieval and Management. this Is Unfortunate as, Invariably, it Is Hardcopy/paper Drawings that Are Mostly Used in Production, Especially in Developing Countries where the Power of CAD/CAM Is yet to Be Fully Harnessed. Accordingly, the DLMS, a Model Successfully Used in a Research Centre in Botswana for over Ten Years Is Proposed.The System Was Further Analysed against and Compared to Three Main Library Classification Systems, Namely, the Dewey Decimal, the Universal Decimal and the Library of Congress Systems. Results Show that the DLMS Is a Better Classification System for Managing Hardcopy Drawings.

Geophysical exploration of an eight million acre oil concession covering southwest Hungary is discussed. During ten years of exploration (1933–1943), about 20,000 torsion balance, 12,000 gravity meter, and 15,000 magnetometer stations were made, and reflection seismograms were recorded at about 2,500 shot points. As a result of this exploration, four oil pools and a gas pool were discovered and a number of geological structures and major faults were located. Gravity, magnetic, and seismic maps showing most of the geophysical data are submitted. Interpretations of the geophysical results, geological data from subsequent drilling, and a schematic tectonic map of southwest Hungary based on the geophysical surveys are also presented.

This study aimed to explore the rules and principles adopted in the Arab-Islamic Classification Systems and tried to identify their scientific methods to determine the relations between sciences. The study followed the comparative analytical method to analyze and compare the Arab-Islamic Classification Systems with the Western modern ones represented in the Dewey Decimal Classification System and the Library of Congress Classification System. The research tries to explore the logic behind classification of sciences in the Arab-Islamic Classification Systems. The findings revealed that the Arab-Islamic Classification Systems follow the same rules and principles of modern classification systems and their types are represented in the types of modern Western classification systems. The study recommends the need to conduct research on the Arab-Islamic Classification Systems and introduce it.

Dewey Decimal Classification is a most popular classification system in the world because of its completeness and most up-to-date. There are many optional number in this classification system, although it rarely to be discussed even it is important to known well about that optional number, especially for a librarian as classifier. This paper is a literature study about Dewey Decimal Classification Edition 23, to describe about optional numbers, particularly the number in relationship with Indonesia’s subject and discipline. This paper is to avoid misunderstanding in interpreted about optional number among librarians, especially for who that does not understand well about optional numbers.
