UDC or DDC: a note about the suitable choice for the National Library of Liechtenstein

Fandino, Marta 12 1900 (has links)
The Universal Decimal Classification (UDC) is currently used in the National Library of Liechtenstein (NLL). Librarians have been using the 1978 German medium edition â Dezimalklassifikation: Internationale Mittlere Ausgabe: FID 550â published by the German Institute for Standardization (Deutsches Institut für Normung - DIN). Since DIN ceased its activity as UDC publisher, there has been no other interest in publishing a German edition of the classification. Hence, the NLL library lacks a suitable and up-to-date UDC edition in German to extend and modernize its content indexing. In order to update information access to its collection, the NLL is faced with two options: reclassifying books to the more recent edition of the UDC or reclassifying to DDC22(Dewey Decimal Classification), recently translated and published in German. In 2007-2008, as part of a graduate library & information science programme internship, research was conducted to assess the suitability of the two classification schemes in supporting collection management and information access in the NLL - with relation to costs, work expenditure and practical classification issues. This text is a brief summary from the final research report.

The Heritage of Facet Analysis in North America: Past Lessons as Pathways for Contemporary Exploration

La Barre, Kathryn January 2009 (has links)
Ranganathan / This paper will contrast the broad contours of Ranganathanâ s legacy in North America with a general assessment of contemporary North American facet applications. It will also offer a potential model for contemporary researchers that outlines heritage facet-analytical protocols currently in use.

Conspectus categorization scheme based on UDC classification used in subject gateways in Czechia

Balikova, Marie 12 1900 (has links)
This paper explores the role of classification and other terminological subject systems in subject gateways showing the Czech experience. The potential of combining a top level classification such as Conspectus with the application of further classified sets of subject access points using UDC is explained. Some examples are given of special subject gateways developed under a general gateway, all interlinked and providing similar interfaces and functionalities. The potential of a common strategy of subject access tools is emphasized, to further improve subject retrieval across the different gateways in a consistent and transparent manner.

Curriculum-based Classification: A Case Study at Southwest College of Naturopathic Medicine Library

Solomon, Daniela January 2005 (has links)
This paper presents classification systems changes that Southwest College of Naturopathic Medicine (SCNM) Library considered necessary in order to organize its collections in ways more readily comprehensible to its users. Because the main purpose of classification is to arrange the materials in ways that facilitate access to information, the classification of the SCNM collections was changed to match more closely the curriculum structure at the College, and thus, to be closer to its users understanding. These changes have been made within areas where the differences between naturopathic and conventional medicine are most obvious, more precisely: diet therapy, acupuncture, homeopathy, physical medicine, botanical medicine, and environmental medicine. Naturopathic medicine uses a natural approach to health and healing. However, many consider naturopathic medicine pseudoscientific. One of the implications of this general attitude towards naturopathy is that within both the Library of Congress and the National Library of Medicine classification systems the naturopathic medicine presence seems to be a minimal afterthought. Although a steadily increasing interest in alternative health use by the general public is observable, both in general and in academic settings, the Library of Congress and the National Library of Medicine have been slow in making any changes in their subject headings and classification systems. The article focuses on changes made within three areas: botanical medicine, homeopathy, and nutrition and diet therapy. The spirit of this process is reflected by the Libraryâ s logo: â A Customized Information Service that Fits Your Natural Health Research Needs.â

Systematics of black and white species of the genus Diaphania Hubner (1818) (Lepidoptera:Pyralidae:Pyraustinae)

Clavijo Albertos, Jose Alejandro January 1990 (has links)
A taxonomic study of 32 species (including 4 new species)belonging to the so-called "black and white" Diaphania is presented. The genus Diaphania and all the species treated are redescribed, except D. antillia Munroe. Diaphania is divided into the "hyalinata", "fumosalis" and "auricollis" species-groups; keys are given for these groups and for the species studied. / Lectotypes and paralectotypes are designated for: Glyphodes columbiana Hampson (male lectotype and three males paralectotypes); Glyphodes eurytornalis Hampson (male lectotype and four males paralectotypes); Glyphodes holophaealis Hampson (male lectotype and seven males paralectotypes); Glyphodes magdalenae Hampson (male lectotype and two males paralectotypes); and Glyphodes oeditornalis (male lectotype). The following new synonymies are presented: Eudioptis aclista Meyrick, Glyphodes semibrunnea Druce = Diaphania argealis (Walker); Glyphodes eurytornalis Hampson = Diaphania lucidalis (Hubner); Glyphodes decapitalis Dognin = Diaphania mirabilis (Druce); Glyphodes holophaealis Hampson = Diaphania indica (Saunders); and Glyphodes niveocilia Hampson = Diaphania translucidalis (Guenee). / Some morphological terms are clarified and renamed or named for the first time: anal tuft; male coremata (= parategumen sclerites in this study); and female coremata (= gynecoremata in this study). A new organ (anepisternal scale organ) associated with possible pheromone production and/or distribution is described. / The monophyly of Diaphania is based in the presence of spatulate scales in anal tuft in both sexes; labial palp with scaling of second segment broad, almost as large as the eye; and the presence of gynecoremata. The genus Omiodes is considered the possible sister-group of Diaphania on the basis of a brief phylogenetic analysis of 21 genera which could be associated with Diaphania. / All species studied are found in tropical and subtropical America, except D. indica (Saunders) which has a pantropical distribution. Host plants for the few species for which information is available mostly belong to the family Cucurbitaceae.

Systematics of Brochymena Amyot and Audinet-Serville and Parabrochymena, new genus (Heteroptera: Pentatomidae: Halyini)

Larivière, Marie-Claude January 1990 (has links)
From the endemic New World halyine genus Brochymena, two genera are recognized. / Brochymena is redefined with 16 taxa. Four synonymies are established: B. marginella Stal = B. carolinensis (Westwood); B. pilatei Van Duzee = B. sulcata Van Duzee; B. laevigata Ruckes = B. myops Stal; B. exardentia Ruckes = B. lineata Ruckes. / Parabrochymena new genus, is erected to contain 8 taxa formerly included in Brochymena. P. inbio and P. ruckesi are newly described. P. barberi diluta is given specific rank. One synonymy is established: B. cuspidata Distant = P. haedula Stal. The status of P. aculeata remains uncertain. / Genera and species groups are described and keys to all taxa provided. As appropriate, for each species, the following are provided: original description citation, synonymies, type material, diagnosis, description, geographical distribution, chorological affinities, phylogenetic relationships, taxonomic comments, natural history, and illustrations of important structural characters. / Evolutionary relationships are discussed based on morphological, ecological, and chorological evidence.
