Knjižnica 51(2007)3-4, 23-40 24 Original scientific article UDC 004.738.52:02 UDC 001.102:004.659 Abstract The article is based on the author’s (Sluga, 2006) research which was the basis for her bachelor’s thesis. The purpose of the research was to analyse and compare the per- formance of different online based information retrieval systems in answering que- ries on library and information science. A case study approach which included four carefully selected cases was used. Search was made in Google, Google Scholar and in appropriate library databases and systems. The performance of these systems was assessed in terms of relevancy, uniqueness, quality, accessibility of documents and precision. The findings demonstrate the advantages and disadvantages of each type. Library databases were highly successful in relevancy, quality and uniqueness of the results and have the ability to retrieve a more precise set of documents. With Google, there were no problems with accessibility, and it offers a high proportion of unique documents. Google Scholar is superior in quality but there are more problems with accessibility. Thus, these systems complement each other.

Vendar: Ali se lahko popularni spletni iskalnik Google primerja s knjižničnimi viri in doseže kvaliteto ter nivo knjižničnih storitev? Očitno Google ima določene prednosti, s katerimi dosega, da se iz dne- va v dan širi krog njegovih uporabnikov. Vse več je predvsem mlajših uporab- nikov, ki se zadovoljijo z informacijami, ki jih najdejo na spletu. Postalo je samou- mevno, da se vsako iskanje začne z Googlom. Vedno bolj se razvijajo tudi spe- cialni iskalniki, kot je Google Scholar, ki omogočajo uporabnikom zamejitev zadetkov na strokovne vire visoke kakovosti. Rast svetovnega spleta tako pred- stavlja velik izziv za tradicionalno iskanje informacij, in prvič se dogaja, da so knjižnice soočene z vedno večjo konkurenco. Zaradi aktualnosti te tematike smo se odločili, da preučimo uporabnost Googla in izbranih infomacijskih virov za področje bibliotekarstva in informacijske znanosti, in sicer po zgledu raziskave, katere avtorja sta Jan Brophy in David Bawden (2005). Izvedli smo raziskavo, s katero smo skušali: - opredeliti prednosti in slabosti izbranih informacijskih virov, - ugotoviti, v katerih primerih je bolje uporabljati spletni iskalnik Google in v katerih knjižnične informacijske vire,
