Schema des Realkatalogs der Königlichen Universitätsbibliothek zu Halle a.S.

"Ich bin der Meinung-, dass jeder Realkatalog einer Bibliothek ein, so zu sagen, individuelles d. h. ein nur für eine bestimmte Bibliothek ausgearbeites Werk sein soll, und dass nur gewisse Grundeintheilungen in der Anlage von Realkatalogen für Bibliotheken, die Werke aus allen Disciplinen enthalten, gemeinsame sein können. Jede Bibliothek, namentlich jede Universitätsbibliothek hat ihr besonderes Gepräge, das ihr die Geschichte der Sammlung aufgedrückt hat.

Roget's Thesaurus

"Roget's Thesaurus is composed of six primary classes. (...) Each class is composed of multiple divisions and then sections. This may be conceptualized as a tree containing over a thousand branches for individual 'meaning clusters' or semantically linked words. Although these words are not strictly synonyms, they can be viewed as colours or connotations of a meaning or as a spectrum of a concept. One of the most general words is chosen to typify the spectrum as its headword, which labels the whole group.

Sygehusvæsnets Klassifikationssystem

"Sygehusvæsnets Klassifikationssystem (SKS) består af flere tusinde koder, som anvendes til at levere struktureret information til forskellige informationssystemer. Koderne spænder over et meget bredt spekter, og at finde lige netop dén kode, som nøjagtigt afspejler en given hændelse eller tilstand, er ikke altid en triviel opgave. Derfor har vi lavet nogle online-værktøjer - de er langt fra perfekte, men dog forhåbentlig en hjælp. Alle værktøjerne er baseret på en online database, som kun indeholder gældende SKS- og SHAK-koder.

"The hospital system classification system (SKS) consists of several thousand codes that are used to provide structured information to different information systems. The codes span a very wide range and to find just that code that accurately reflects a given event or condition is not Always a trivial task. Therefore, we have made some online tools - they are far from perfect, but hopefully help. All tools are based on an online database that contains only SKS and SHAK codes. The database is updated continuously , And the data content of the tools is thus always updated. "
