- 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.

- Rez. in: KO 38(2011) no.4, S.360-361 (M.P. Satija): "The 20th edition of the celebrated Sears List (1sted.1923) published in June 2010 sets a new cycle of three year revision. Earlier it was three and a half years to synchronize with the publication of the new edition of the Abridged Dewey revised after every seven years. In the days of constantly updated WebDewey, it is no more a constraint. For the first time Sears List has been released simultaneously in online database format accessible to licensed subscribers. Responding to the environmental changes the basic edition is the online one whose content is designed in MARC authority. Print edition is now a derivative of the MARC data. The editors keep tabs on the changing information seeking behavior of users and how OPACs are accessed; yet the editors or the publishers never discuss the mechanisms of designing a new edition. The new edition features more than 300 new subject headings suggested by librarians from different types of libraries, vendors of bibliographic records, indexers and subject specialists at the H.W. Wilson Company. Every new edition incorporates advances in vocabulary control, changing approaches of library users for subject access and even in the worldwide use of the English language. Each edition of the Sears List strengthens and continues the policies and consolidates the reforms that began with the 15th edition (1994). It is indeed an era of innovations in Sears. The latest knowledge from information science and information seeking behavior has been deployed to modernize the internal structure and grammar of the Sears List. Continuing adaptation constitutes the key to its success and popularity in the shifting sands of the information-seeking behavior of users. But the List is still a living manifestation of the principles of subject cataloguing put forth by C.A. Cutter (1837-1903).

- Abstract
- LCSH are increasingly seen as 'the' English language controlled vocabulary, despite their lack of a theoretical foundation, and their evident US bias. In mapping exercises between national subject heading lists, and in exercises in digital resource organization and management, LCSH are often chosen because of the lack of any other widely accepted English language standard for subject cataloguing. It is therefore important that the basic nature of LCSH, their advantages, and their limitations, are well understood both by LIS practitioners and those in the wider information community. Information professionals who attended library school before 1995 - and many more recent library school graduates - are unlikely to have had a formal introduction to LCSH. Paraprofessionals who undertake cataloguing are similarly unlikely to have enjoyed an induction to the broad principles of LCSH. There is currently no compact guide to LCSH written from a UK viewpoint, and this eminently practical text fills that gap. It features topics including: background and history of LCSH; subject heading lists; structure and display in LCSH; form of entry; application of LCSH; document analysis; main headings; topical, geographical and free-floating sub-divisions; building compound headings; name headings; headings for literature, art, music, history and law; and, LCSH in the online environment. There is a strong emphasis throughout on worked examples and practical exercises in the application of the scheme, and a full glossary of terms is supplied. No prior knowledge or experience of subject cataloguing is assumed. This is an indispensable guide to LCSH for practitioners and students alike from a well-known and popular author.

- - Retrievalmöglichkeiten - Ein Test der Retrievalmöglichkeiten von Zeitangaben in den Online-Katalogen der LoC, BnF und DDB zeigte, dass für ein optimales Suchergebnis viele Recherche-Schritte und Regelwerkskenntnisse notwendig sind, eine aus Nutzersicht unbefriedigende Bilanz. Zum Beispiel muss für Suchanfragen nach Jahreszahlen der Zeitraum genauso angegeben werden, wie es bei der Indexierung geschah, oder eine Suche mit Epochenbegriffen und zeitimmanenten Schlagwörtern erfordert die genaue Kenntnis der Ansetzungsregeln für solche Deskriptoren. Die angebotenen Schlagwortketten sind eine Suchhilfe, erlauben aber keine Sortierung nach der Zeitenabfolge. Der größte Mangel ist, dass alle Zeitcodierungen nur als Zeichen, nicht als Zahlen, erkennbar sind, sodass bei der Suche nur ein Zeichenabgleich erfolgt und keine Sortierung nach Zahlen möglich ist. Jutta Frommeyer stellt die Retrievalmöglichkeiten der drei genannten Bibliothekskataloge verschiedenen anderen Datenbanken gegenüber, die eine Suche nach Zeitangaben anbieten. Die Suchmöglichkeiten bei den Allgemeinenzyklopädien (»Encyclopedia Britannica«, »Brockhaus-Enzyklopädie«, »Encarta«) sind vielfältig und elaboriert. Zeitimmanente Begriffe sind chronologisch angeordnet und auch grafisch durch Zeitschienen dargestellt, von denen aus auf ein Jahr oder einen Zeitbegriff gesprungen werden kann. Die Datenbank »Historical abstracts« bietet den Zeitraum, der in einem Dokument behandelt wird, über eine spezielle Codierung an. Die »Jahresberichte für deutsche Geschichte« bieten für das Zeitretrieval eine Tabelle mit 14 verschiedenen Möglichkeiten; die weitere Differenzierung der Suchanfrage erfolgt hier durch andere Sacherschließungselemente wie eine ausgefeilte Klassifikation und eine Schlagwortliste. - Modell zum optimalen Zeitretrieval - Aufgrund ihrer Untersuchungen entwickelt die Autorin ein theoretisches Modell für ein optimales Zeitretrieval in allgemeinbibliografischen Datenbanken mit den drei Elementen Zeitcode, Chronikcode und Chroniknormdatei. Damit die Zeitcodierungen als Zahlen und nicht als Zeichen erkennbar sind, müssen sie in einem besonderen numerischen Feld (Zeitcode) abgelegt werden; mit der Möglichkeit, nach Zeiträumen zu suchen (Größer-, Kleiner- und Gleichoperatoren). Die Zeitspannen von Zeitbegriffen werden als Chronikcode in der gleichen Datenstruktur wie der Zeitcode bei den Normdatensätzen ergänzt. Für bestimmte Zeitbegriffe ist eine Normierung notwendig (z. B. Mittelalter). Bei kulturkreisabhängigen Zeitbegriffen kann die zeitliche Codierung verschieden aussehen. Die Chroniknormdatei soll die chronologische Relation der zeitimmanenten Begriffe darstellen und bei umfassenden Zeitspannen große Trefferzahlen vermeiden. Da zeitimmanente Begriffe über alle Sachgebiete streuen, muss für das Retrieval eine sachliche Einschränkung gegeben sein. Jutta Frommeyer schlägt dafür eine international angewandte Klassifikation vor. Die Autorin stellt ein Retrievalmodell dar, um das Zusammenwirken von Zeitcode,Chronikcode und Chroniknormdatei zu demonstrieren. Dabei hat sie sich an der heutigen Menü-Oberfläche für OPACs orientiert und ein neues Suchfeld »Zeitabschnitt« mit verschiedenen Unterteilungen eingeführt. Ihre Beispiele sind nachvollziehbar und verdeutlichen ihren Vorschlag. Die Umsetzung eines solchen Modells hat Auswirkungen auf die vorhandenen Datenstrukturen; auch wird eine Annäherung der Regeln für die Schlagwortvergabe nach RSWK, Rameau und LCSH notwendig sein, wenn so eine Suche international angeboten werden soll.
