- Abstract
- Reports results of a study of the use of metaphors as problem solving mechanisms by novice searchers of bibliographic databases. Metaphors provide a framework or 'familiar structure' of credible associations within which relationships in other domains may be considered. 28 students taking an undergraduate course in information retrieval at Sydney University of Technology, were recorded as they 'talked through' a search on a bibliographic retrieval system. The transcripts were analyzed using conventional methods and the NUDIST software package for qualitative research. A range of metaphors was apparent from the language use by students in the search process. Those which predominated were: a journey; human interaction; a building or matching process; a problem solving process, and a search for a quantity. Many of the studentes experiencing the interaction as a problem solving process or a search for quantity perceived the outcomes as successful. Concludes that when memory for operating methods and procedures is incomplete an unconscious approach through the use of a conceptual system which is consonant with the task at hand may also lead to success in bibliographic searching

- Abstract
- Automatic content indexing is one of the innovations that are increasingly changing the way libraries work. In theory, it promises a cataloguing service that would hardly be possible with humans in terms of speed, quantity and maybe quality. The German National Library (DNB) has also recognised this potential and is increasingly relying on the automatic indexing of their catalogue content. The DNB took a major step in this direction in 2017, which was announced in two papers. The announcement was rather restrained, but the content of the papers is all the more explosive for the library community: Since September 2017, the DNB has discontinued the intellectual indexing of series Band H and has switched to an automatic process for these series. The subject indexing of online publications (series O) has been purely automatical since 2010; from September 2017, monographs and periodicals published outside the publishing industry and university publications will no longer be indexed by people. This raises the question: What is the quality of the automatic indexing compared to the manual work or in other words to which degree can the automatic indexing replace people without a signi cant drop in regards to quality?
