    Abstract
    The system is available both in print and online versions. Names a few new subject headings in areas like science, technology, engineering and medicine (STEM). In this edition, there are a total of 1,600 new headings making it a total of 12,000+ preferred headings meant for subject access in small and medium sized libraries. This unprecedented increase of about 1,600 headings is mostly due the complete incorporation of the Canadian Sears last published independently in 2006. Also critically examines inconsistencies in a few headings. Concludes to say the new edition in resplendent, hard binding maintains its stellar reputation of a handy list of general subject headings both for applications and a teaching resource.

    "Das Unternehmen E Ink, im Jahr 1997 von Mitarbeitern des Massachusetts Institute of Technology (MIT) in Boston gegründet, hatte schon 1999 ein Papier ähnliches Material in Kaufhäusern der Region als digitale Werbetafeln ausprobiert. Die Anzeige ließ sich mit einer Fernsteuerung - ohne umständliche Montagen - blitzschnell umschreiben. Händler konnten so Preise ändern oder Sonderangebote hinzufügen. Doch mehr als drei Zeilen mit vierschrötigen Buchstaben waren auf dem elektronischen Plakat nicht zu platzieren, Doch die Idee hatte es in sich. Die neuartigen Displays bestehen aus zwei dünnen Plastikfolien, überzogen mit einem filigranen Netz haarfeiner Leitungen. Zwischen den transparenten Filmen sind Millionen von Mikrokapseln verankert. Im Inneren der durchsichtigen Kügelchen schwimmen in einer trägen blauen Flüssigkeit winzige weiße Farbpartikel. Die Tonerteilchen sind negativ geladen. Wird eine Spannung angelegt, schnellen die Farbkörnchen in den Ölkapseln nach oben oder unten. Buchstaben und Zeichen entstehen mit dem Passiv-Verfahren, wenn an den Kreuzungspunkten der Drähte die Spannung einen Schwellenwert überschreitet. Sind die Farben einmal ausgerichtet, verharren sie ohne weitere Energiezufuhr. Erst ein erneuter Stromstoß ändert die Schrift auf den Tafeln. Anfang April stellten die E Ink-Ingenieure ein neues Display vor. Um mehr Bildpunkte unterzubringen, griffen sie auf ein Aktiv-Verfahren zurück- Statt eines Drahtgeflechts werden die Folien mit Transistoren bestückt. Damit lassen sich die Pixel genauer ansteuern; der Kontrast wird besser, die Lettern feiner. Der Lucent-Konzern, Betreiber der Bell Labs und ebenfalls Kompagnon bei E Ink, entwiekelt seit 1997 eine solche Methode. Dazu bedienen sich die Forscher einer alten Technik- des Gummiabdrucks. Die Stempel werden von einem Siliziumchip abgefonnt. Anschließend wird die Gummifläche mit säurefester Farbe bestricben und auf eine hauchdünn mit Gold beschichtete Trägerfolie gepresst. Das nicht geschützte Metall wird hinterher im Ätzbad abgewaschen, die Schaltkreise bleiben stehen.
    "Dieses Display demonstriert zum ersten Mal eine realistische Anwendung eines Plastiktransistors", begeistert sich Tom Uhlman, Lucent-Manager. Das fertige Kunststoffsandwich braucht nur noch ein handelsübliches Treiberprogramm, um als Display zu funktionieren. Ebenso wichtig- Das Verfahren eignet sich ausgezeichnet für eine Massenproduktion. Die vorgestellten Bögen waren noch klein und wenig auflösend. Auf zwölf mal zwölf Zentimeter, etwas mehr als das Viertel einer DIN-A4-Seite, verteilten sich 256 Bildpunkte, mit denen sich gerade mal sechs Buchstaben darstellen ließen. Wichtiger war John Rogers allerdings der Handschlag zwischen Buch und Bildschirm. ,Das Material hat das Aussehen und die Anmutung von herkömmlichem Papier«, schwärmt der Lucent-Wissenschaftler, ,aber es ist rekonfigurierbar wie ein normaler Computerbildschirm." Mehrere tausendmal, schätzen Fachleute, kann der Plastikmonitor neu beschrieben werden. Vergangene Woche präsentierten Philips und E Ink dann im kalifornischen San José einen ausgereiften Fünf-Zoll-Monitor. Der im rasanten Tempo entwickelte Prototyp präsentiert mit 80 Bildpunkten pro Inch schwarze Texte auf weißem Grund. ,Sein oder nicht sein" leuchtete den Teilnehmern eines Seminars Shakespeares Schicksalsfrage entgegen. Eine farbige Version des dünnen Displays hat das Untemehmen aus Cambridge angekündigt wenngleich mit schlechterer Auflösung. Bevor das Material zur ewigen Zeitung wird, tritt es wohl seinen Siegeszug als superflacher Monitor an. Denn im Gegensatz zu anderen Bildschirmen muss es nicht von hinten ausgeleuchtet werden.
    Verglichen etwa mit LCD-Monitoren verblasst die Schrift nicht im Sonnenlicht und ist auch von der Seite zu lesen. Deshalb taugt die Erfindung besonders für mobile Geräte und Handheld-Computer, aber auch zum flexiblen Preisschild oder Kontrollzettel für Lebensmittel. Unschlagbarer Vorteil ist der geringe Energieverbrauch: tausendmal weniger als der Bildschirm eines Notebooks. "Wir haben zusammen mit weltweit führenden Herstellern die nächste Generation von Displays für elektronische Geräte entwiekelt", freut sich E-Ink-Chef Jim Juliano. Die Idee dazu hatte ein Xerox-Forscher schon vor 25 Jahren. Nicolas Sheridon suchte nach neuartigen Materialien für die Mattscheiben. Denn die Bildschirme waren damals arge Flimmerkisten, ihre Darstellung tendierte eher ins Dunkle. Die von Sheridon entwickelte Technik arbeitet ähnlich wie die E Inks. Allerdings sind die Pigmentperlen in den Kapseln Dipole- Sie besitzen einen elektrischen Plusund einen Minuspol. Zudem sind sie - entsprechend dieser Polung - zweifarbig, eine Hälfte etwa rot, die andere weiß. Je nach anliegender Spannung dreht sich einer der Farbtöne nach oben. Für die Verwertung des Gyricon genannten Produkts hat das amerikanische Unternehmen im vergangenen Jahr eigens eine Firma gegründet. Xerox-Entwickler Nick Sheridon ist zuversichtlich: "Die Stärke von Gyricon ist seine absolute Flexibilität. Die Bandbreite der Einsatzmöglichkeiten lässt sich heute noch gar nicht ganz einschätzen." Den Durchbruch für seine neue Papiersorte erhofft sich der Kopierkonzern vor allem von digitalen Etiketten und Werbeflächen. in Geschäften. Das Buch der Zukunft wird vermutlich noch etwas auf sich warten lassen - Buchhändler und die Regalabteilung von Ikea wird es freuen, Wälder weniger. "Die technischen Dinge sind zwar gelöst" sagt Joe Jacobson, MIT-Forscher und Mitbegründer von E Ink. "Die Frage ist, ob die Mensehen bereit sind für einen neuen Weg, Informationen zu lagern und zu lesen."

    Abstract
    Discussion of the results and consequences of the automation project named thesaurus/concordance project, carried out at the DUT Library. The aim of the project was, by making the subject headings and their corresponding classification codes machine readable, to produce periodically cumulative lists, classifies lists, lists per subject fields, alphabetical lists of inverted subheadings and geographical names with their corresponding main headings and notations

    Abstract
    The history of the Library of Congress Subject Headings is traced, from its beginnings with the implementation of a dictionary catalog at the Library of Congress in 1898 to the present day. The author describes the most significant changes which have occurred in LCSH policies and practices during the 100-year period. Events noted near the end of the century indicate an increased willingness on the part of' the Library of Congress to involve the larger library community in the creation or revision of subject headings and other decision-making regarding the LCSH system. Finally, the author provides a summary of the other contributions to this collection of essays, a collection which celebrates the "centennial" of the world's most popular library subject heading language

    Abstract
    Surveys conducted during the last four years under the auspices of the International Federation of Library Associations and Organizations (IFLA) reveal that the Library of Congress Subject Headings is heavily used in national libraries outside of the United States, particularly in English-speaking countries. Many other countries report using a translation or adaptation of LCSH as their principal subject heading language. Magda Heiner-Freiling presents an analysis of the IFLA data, which also includes information on the classification schemes used by the libraries and whether or not the libraries have produced a manual on the creation and application of subject headings. The paper concludes with an Appendix showing the complete data from the 88 national libraries that respond to the surveys

    Abstract
    Lecture given at the AIBM conference, Karlsruhe, Sep 95. The thesaurus appeared 1st in 1982, produced according to DIN standard 1463. This standard is largely adhered to, with 2 deviations: the controlled vocabulary is rather universal, covering more than 1 musical field, and descriptors are used as systematic collection points, with non-decriptors as subordinate headings. The 1994 edition has widened its contents range. There are still problems with ambiguity of headings and titles

    Abstract
    Within the multilingual framework of the CrissCross project, MACS (Multilingual Access to Subjects) has continued its work. MACS has developed a prototype of mappings between three vocabularies: the LCSH (Library of Congress Subject Headings), RAMEAU (Répertoire d'autorité-matière encyclopédique et alphabétique unifié) and the SWD (Schlagwortnormdatei). A database with a Link Management System (LMI), which allows for an easy linking between English, French and German subject headings, was created. The database started working with headings from the disciplines sports and theatre, but by now headings from all other fields of knowledge have been included as well. In 2008-2010, equivalencies between English and French headings which had been produced by the Bibliothèque nationale de France have been completed with the most important German SWD topical terms. Thus, more than 50.000 trilingual links are now available and can be used in different retrieval scenarios. It is planned to use them in The European Library (TEL) in order to support multilingual searches over all European National Library collections. The article informs about the project workflow, methodology of mapping and future applications of MACS links.
