The master degree thesis focuses on the comparison of the uses of electronic magazines of Central Technical Library consortiums. The data used refer to the actual use of electronic magazines. The objective of the thesis is to ascertain which electronic magazines have the widest readership, which agents and suppliers are predominant in Slovene libraries. Furthermore, the thesis aims to establish the prices of electronic magazines and additional financial sources Slovene libraries use to supply electronic magazines. The methods used in the thesis are analytical and statistical. The consortiums are evaluated according to the accepted methodology, for it is this methodology that evaluates the registered magazines. My aim was to examine whether consortiums can be measured with the same measurement as individual registrations of magazines by libraries. From the methodology used by Slovenian Research Agency, the research uses only the data on accessibility, quality and importance of the ordered international scientific literature and databases as well as the frequency of use. The comparison of consortiums reveals that in the evaluation of consortiums, the crucial data are: firstly, the quality and importance of the ordered international scientific literature and databases and, secondly, the data on the frequency of use. The results show that magazines with a high Impact Factor do not necessarily have a high rate of use. There is no strong connection between the price and the IF either. I have established that there is not a higher number of publishing by Slovene authors either in magazines with a higher IF or in magazines with a higher statistics of use.
