Some issues in the classification of literature according to UDC and their interpretation in the practice of the National and University Library in Zagreb

U radu se prikazuje praksa klasifikacije književnosti u NSK, i to dijela građe koji se zbog svog oblika i sadržaja može klasificirati na više načina. To se ponajprije odnosi na nefikcionalnu prozu: eseje, autobiografije, biografije, memoare, putopise. Dio teksta posvećen je problematici odnosa proze i poezije, npr., pjesme u prozi i kratke proze. Također, budući da i klasifikacija književnosti prema pojedinim jezicima, u jednom dijelu građe, nije bez teškoća, prikazan je način obrade djelâ koja legitimno pripadaju dvjema književnostima.The article discusses the classification of literature according to Universal Decimal Classification (UDC) in relation to the practice of the National and University Library in Zagreb (Croatia). The author draws attention to documents that can be classed in other disciplines as well as literature and gives examples of such works in non-fictional prose: essays, (auto)biographies, memoires and travel diaries. The article also discusses some difficulties in content analysis and alternatives in classification for documents that fall in between forms and genres such as, e.g. those between prose and poetry. Finally, the article analyses the problem of having a language of the literary works as a criterion for classification of literature which causes the problem in collocation of works by an author who writes in different languages and thus belong to different literatures
