The primary purpose of the research was a comparative analysis of computerized integrated
library systems (WebOPAC) based on and/or providing Web 2.0
services, by reviewing several important library systems of Hungary and the USA.
The research was conducted in all of the 19 Hungarian county libraries and the
libraries of 67 higher education institutions in Hungary. Besides, the integrated
library systems of 39 university libraries in the USA were also analyzed. Both
inductive and quantitative methods were applied.
In this study, the selected Hungarian and American university libraries were
studied from the point of view of Web 2.0 services. The main features of Web
2.0 services provided by those libraries were compared. In addition, content
elements and statistical data were analyzed, major differences were referred
to, and additional effective internet services were suggested to be introduced
in the future.
