Users of the dLibra system may be divided into three common types:
Administrator - manages digital library (creates users and groups of users, grants rights to users and groups), can create and modify library structure, can use all of the dLibra system applications (administrator, editor, WWW) but generally uses administrator application,
Editor - creates digital library (adds new digital objects to library, creates or imports description for objects, groups objects, generally has limited access to administrator application, uses editor application,
Reader - dLibra system user which has access only to web pages (WWW) placed on the Internet, can browse and read digital objects created and made available by the editor, cannot use neither editor nor administrator application, every person which visits dLibra web pages is treated as a reader.
These are three types of uses commonly used in digital libraries based on dLibra. Each has different duties and nature. Administrator takes care of a digital library as a whole, editor cares about the content of the digital library according to limits specified by the administrator, reader uses WWW to access documents (publications) stored by the editor in the digital library.
