Abstract

Das Internet verändert die Rahmenbedingungen des wissenschaftlichen Publikationswesens einschneidend. Wissenschaftliche Dokumente sind zunehmend elektronisch verfügbar und beginnen, die klassischen Wissenschaftsmedien wie Fachbücher und Fachzeitschriften zu verdrängen. Die Implementierung eines elektronischen Publikationsprozesses ist Voraussetzung für die erfolgreiche Verbreitung wissenschaftlicher Dokumente per Internet. Die Umsetzung setzt jedoch die Einhaltung bestimmter Vorgaben und Regularien voraus, sonst drohen Inkompatibilitäten zwischen den Systemen. Im Kontext von Urheberrechtsnovellierung und Open Access-Bewegung erläutert dieser Beitrag technische und rechtliche Rahmenbedingungen von Online-Publikationen und stellt Projekte und Initiativen vor, die sich auf dem Feld des wissenschaftlichen Publikationswesens betätigen. Ausführlich wurden Problembereiche des aktuellen Publikationsprozesses von Abschlussarbeiten im Studiengang Internationales Informationsmanagement an der Universität Hildesheim mit Hilfe von Interviews untersucht. Auf Grundlage der Zustandsanalyse wurde anschließend der elekronische Publikationsprozess modelliert.

"Das Portal "Verteilte Digitale Inkunabelbibliothek (vdlb)" ist seit Mitte des Jahres online. Es stehen mehr als 550 digitalisierte Inkunabeln zur Verfügung. Mit der gemeinsamen Digitalisierung von mehr als 1.000 der geschätzten 27.000 Inkunabeln wird ein signifikanter Teil erschlossen sein. Im Workshop am 2./3.11.2005 an der Universität Köln wird beraten: - Welches Interesse haben wir an Inkunabeln und warum sollten sie über Internet zur Verfügung gestellt werden? - Wie ist das Angebot des vdlb-Portals methodisch und inhaltlich zu bewerten? - Welche Perspektiven gibt es für eine Gesamtdigitalisierung aller Inkunabelausgaben und für die Konstituierung eines zentralen Portals?"

Rez. in: KO 31(2004) no.2, S.117-118 (D. Campbell): "This excellent volume offers 22 papers delivered at an IFLA Satellite meeting in Dublin Ohio in 2001. The conference gathered together information and computer scientists to discuss an important and difficult question: in what specific ways can the accumulated skills, theories and traditions of librarianship be mobilized to face the challenges of providing subject access to information in present and future networked information environments? The papers which grapple with this question are organized in a surprisingly deft and coherent way. Many conferences and proceedings have unhappy sessions that contain a hodge-podge of papers that didn't quite fit any other categories. As befits a good classificationist, editor I.C. McIlwaine has kept this problem to a minimum. The papers are organized into eight sessions, which split into two broad categories. The first five sessions deal with subject domains, and the last three deal with subject access tools. The five sessions and thirteen papers that discuss access in different domains appear in order of in creasing intension. The first papers deal with access in multilingual environments, followed by papers an access across multiple vocabularies and across sectors, ending up with studies of domain-specific retrieval (primarily education). Some of the papers offer predictably strong work by scholars engaged in ongoing, long-term research. Gerard Riesthuis offers a clear analysis of the complexities of negotiating non-identical thesauri, particularly in cases where hierarchical structure varies across different languages. Hope Olson and Dennis Ward use Olson's familiar and welcome method of using provocative and unconventional theory to generate meliorative approaches to blas in general subject access schemes. Many papers, an the other hand, deal with specific ongoing projects: Renardus, The High Level Thesaurus Project, The Colorado Digitization Project and The Iter Bibliography for medieval and Renaissance material. Most of these papers display a similar structure: an explanation of the theory and purpose of the project, an account of problems encountered in the implementation, and a discussion of the results, both promising and disappointing, thus far. Of these papers, the account of the Multilanguage Access to Subjects Project in Europe (MACS) deserves special mention. In describing how the project is founded an the principle of the equality of languages, with each subject heading language maintained in its own database, and with no single language used as a pivot for the others, Elisabeth Freyre and Max Naudi offer a particularly vivid example of the way the ethics of librarianship translate into pragmatic contexts and concrete procedures. The three sessions and nine papers devoted to subject access tools split into two kinds: papers that discuss the use of theory and research to generate new tools for a networked environment, and those that discuss the transformation of traditional subject access tools in this environment. In the new tool development area, Mary Burke provides a promising example of the bidirectional approach that is so often necessary: in her case study of user-driven classification of photographs, she user personal construct theory to clarify the practice of classification, while at the same time using practice to test the theory. Carol Bean and Rebecca Green offer an intriguing combination of librarianship and computer science, importing frame representation technique from artificial intelligence to standardize syntagmatic relationships to enhance recall and precision.
The papers discussing the transformation of traditional tools locate the point of transformation in different places. Some, like the papers an DDC, LCC and UDC, suggest that these schemes can be imported into the networked environment and used as a basis for improving access to networked resources, just as they improve access to physical resources. While many of these papers are intriguing, I suspect that convincing those outside the profession will be difficult. In particular, Edward O'Neill and his colleagues, while offering a fascinating suggestion for preserving the Library of Congress Subject Headings and their associated infrastructure by converting them into a faceted scheme, will have an uphill battle convincing the unconverted that LCSH has a place in the online networked environment. Two papers deserve mention for taking a different approach: both Francis Devadason and Maria Ines Cordeiro suggest that we import concepts and techniques rather than realized schemes. Devadason argues for the creation of a faceted pre-coordinate indexing scheme for Internet resources based an Deep Structure indexing, which originates in Bhattacharyya's Postulate-Based Permuted Subject Indexing and in Ranganathan's chain indexing techniques. Cordeiro takes up the vitally important role of authority control in Web environments, suggesting that the techniques of authority control be expanded to enhance user flexibility. By focusing her argument an the concepts rather than an the existing tools, and by making useful and important distinctions between library and non-library uses of authority control, Cordeiro suggests that librarianship's contribution to networked access has less to do with its tools and infrastructure, and more to do with concepts that need to be boldly reinvented. The excellence of this collection derives in part from the energy, insight and diversity of the papers. Credit also goes to the planning and forethought that went into the conference itself by OCLC, the IFLA Classification and Indexing Section, the IFLA Information Technology Section, and the Program Committee, headed by editor I.C. McIlwaine. This collection avoids many of the problems of conference proceedings, and instead offers the best of such proceedings: detail, diversity, and judicious mixtures of theory and practice. Some of the disadvantages that plague conference proceedings appear here. Busy scholars sometimes interpret the concept of "camera-ready copy" creatively, offering diagrams that could have used some streamlining, and label boxes that cut off the tops or bottoms of letters. The papers are necessarily short, and many of them raise issues that deserve more extensive treatment. The issue of subject access in networked environments is crying out for further synthesis at the conceptual and theoretical level. But no synthesis can afford to ignore the kind of energetic, imaginative and important work that the papers in these proceedings represent."

Abstract

Die digitale Bibliothek, in der alles mit allem verlinkt ist, und man mit wenigen Klicks zur gewünschten Information gelangt, ist nach wie vor ein Traum vieler Bibliothekare und Benutzer. In der Realität aber existieren heterogene Informationssysteme nebeneinander: Online-Datenbanken, Aggregatordatenbanken, A&I-Datenbanken, Plattformen für E-Journals, OPACs. Zwischen diesen verschiedenen Systemen muss der Nutzer nun hin- und herschalten, um die gewünschte Information zu erhalten. Dass eine Verlinkung der verschiedenen elektronischen Ressourcen der Bibliothek ein Desiderat ist, hat inzwischen auch die Industrie erkannt. Es sind bereits erste Systeme auf dem Markt, die eine Navigation in heterogenen Informationsquellen ermöglichen. Zu nennen ist hier in erster Linie ExLibris SFX. Auch EBSCO hat mit LinkSource eine auf openURL basierte Lösung vorgelegt, um alle verfügbaren Quellen in eine Suchanfrage einzubinden. Diese Systeme sind prinzipiell sehr vielversprechend und von der Bibliothek sehr komfortabel zu managen, bewegen sich aber derzeit in einem preislichen Rahmen, der von den wenigsten Bibliotheken noch zusätzlich zu den ohnehin schon hohen Kosten für elektronische Ressourcen aufgebracht werden kann. An der UB Osnabrück und SuUB Bremen wurden daher Überlegungen angestellt, wie man ohne diese kostenpflichtigen Zusatzdienste die verschiedenen elektronischen Angebote der Bibliothek besser miteinander verknüpfen könnte. Konkret lautete die Fragestellung so: "Wie komme ich nach einer Recherche in einer bibliografischen Online-Datenbank zum Volltext?" Die meisten OnlineDatenbanken sind immer noch rein bibliografische Datenbanken, die allerhöchstens ein Abstract anbieten (A&I-Datenbanken). Erscheint ein Rechercheergebnis dem Benutzer so interessant, dass er gern den Volltext des betreffenden Artikels oder des Buches einsehen möchte, so hat er dazu mehrere Möglichkeiten: Die einfachste Möglichkeit liegt darin, den Volltext in elektronischer Form aufzurufen. Besteht diese Möglichkeit nicht, so muss er im OPAC recherchieren, ob der gesuchte Titel zumindest in gedruckter Version in der Bibliothek vorhanden ist. Ist dies nicht der Fall, so hat er die Möglichkeit, den Titel per Fernleihe oder document delivery zu bestellen. Diese drei Schritte - Aufrufen des Volltextes, Recherche im OPAC, Fernleihbestellung - sollten für den Benutzer dadurch vereinfacht werden, dass ent sprechende Links in die Online-Datenbanken integriert werden. So kann das aufwändige "kopieren und einfügen"- Verfahren entfallen. Die Einrichtung dieser verschiedenen Links brachte administrative, technische und lizenzrechtliche Probleme mit sich. Online-Datenbanken werden von verschiedenen Anbietern auf den Markt gebracht: von international agierenden Firmen bis hin zu kleinen Körperschaften. Es musste bei jedem Anbieter geklärt werden, welche Verlinkungen technisch und lizenzrechtlich möglich sind. Links zum elektronischen Volltext sind für den Nutzer sicherlich die ideale Lösung, denn so kann er vom Büro oder CIP-Pool aus den Artikel lesen bzw. ausdrucken, ohne in die Bibliothek gehen und dort nach der Print-Ausgabe suchen zu müssen. Bei Volltextlinks muss man zwischen zwei Arten von Links unterscheiden: Institutionsunabhängige Links sind zentral für alle Abonnenten der Online-Datenbank eingerichtet und werden immer angezeigt, unabhängig davon, ob die Bibliothek einen lizenzierten Volltextzugriff auf die betreffende elektronische Ressource hat. Institutionsabhängige Links sind nur für die elektronischen Ressourcen eingerichtet, für die die Bibliothek einen lizenzierten Zugang besitzt.

Abstract

PhysNet offers online services that enable a physicist to keep in touch with the worldwide physics community and to receive all information he or she may need. In addition to being of great value to physicists, these services are practical examples of the use of modern methods of digital libraries, in particular the use of metadata harvesting. One service is PhysDoc. This consists of a Harvest-based online information broker- and gatherer-network, which harvests information from the local web-servers of professional physics institutions worldwide (mostly in Europe and USA so far). PhysDoc focuses on scientific information posted by the individual scientist at his local server, such as documents, publications, reports, publication lists, and lists of links to documents. All rights are reserved for the authors who are responsible for the content and quality of their documents. PhysDis is an analogous service but specifically for university theses, with their dual requirements of examination work and publication. The strategy is to select high quality sites containing metadata. We report here on the present status of PhysNet, our experience in operating it, and the development of its usage. To continuously involve authors, research groups, and national societies is considered crucial for a future stable service.

Abstract

Examines the use of the Z39.50 Information Retrieval protocol for provision of access to its collections. Z39.50 offers a translation of different search engines developed by library systems suppliers and online database hosts. Traces its development and describes its abstraction and metalanguage, and the TCP/IP and OSI layer. It is being further developed in project ONE - OPAC Network in Europe, and European Union Library Plan project which began in Jan 95, of which the British Library is a partner. It aims to link national library catalogues in an open standards and telecommunications network, and to achieve interoperability by use of Z39.50. Describes the project so far, agreements made, and future developments

Abstract

Subject-based retrieval in distributed resources is a current problem in online searches for bibliographic references. Building portals to similar resources is only the ferst step, the subsequent navigation via different search interfaces presents certain difficulties. To make retrieval easier it is necessary to adapt these different resources. Potential approaches (standardisation as opposed to "cross-walks") and methods (automated as opposed to intellectual effort) will be discussed. This includes a Brief appraisal of the future of work with multilingual terminology: - The "classical" approach (Multilingual Thesauri), - The "Internet" approach (linking) Recent developments in mono- and multilingual environments will be presented (MACS, CARMEN, Economics Crosswalk).
