Digital Libraries (DLs), available via www were reviewed. Four DLs
Gutenberg, 24×7, Netlibrary and Ebrary were chosen. A comprehensive
inventory consisted of general information, search features, display options
and unique features was composed for comparing the interfaces of these
DLs. Then chosen interfaces were compared and evaluated. Results showed
that Netlibrary scored higher according to the specified criteria. However, in
designing interface for such DLs, designers should take into considerations

Electronic Book, Database, Digital Library, User Interface, Ebrary, Netlibrary, 24x7, Gutenberg INTRODUCTION This article presents the findings of a study of the user interfaces of four Digital Libraries (DLs) offering access to e-books.
In a 1993 study, Bev Kennedy [12] used ERIC database to compare numerous search features offered through the end-user systems of First Search, After Dark and Knowledge Index [12].
[9], Groote [8] and Schneider [20] evaluated and compared different versions of Medline database and in some cases introduced criteria for designing better user interfaces.
As the above literature review shows, almost all of the works cited were works done on e-journal DLs. In all databases we searched, just a few works were found regarding different aspects of e-book DLs. However, we did not find any study regarding comparison of e-book DLs. METHODOLOGY Research into user interfaces of IR systems usually demands specific approaches to evaluation, i.
The first reason for choosing e-book used in this study was that the user interfaces of these systems should be different enough for a meaningful comparison.
2. According to proposed criteria in Tables 1-4, which of these DLs have better interface with more features and options to support a user?
Totally, Gutenberg received 25 scores out Evaluation & Comparison of Free and Commercial User Interfaces of Digital Libraries 5O of 51 (Table5).
