Naviga is advanced tool for access and administration of electronic information sources which provides brand new options for simultaneous searching of electronic information sources from one interface and access according to rights and licence conditions to all authorised users. It provides easy and comfortable access to actual licenced digital sources - electronic journals, books, encyclopaedias etc.

Naviga offers access to user´s web interface for regular users. It enables a connection with the external publishers´ sources with use of standard (Z39,50, SRW, SRU) or proprietary protocols and also a connection of internal sources such as digital archives, grey literature, perhaps of other similar bases.

Naviga integrates all electronic information sources to one access point, both, the internal (built-in) references in a local database managed directly by the system administrator, and the external sources available through optional connectors. The service supports query languages PGF, RPN, CQL and operates with operating systems Linux and Solaris.

Because the system saves information about users and their access rights in internal database, it is possible to connect authentication of users to other external source, such as LDAP server, perhaps other database authentication.

Naviga enables to divide the sources by their content into thematic groups and scientific areas and also to list them by the publishers´ name. This eases the orientation in publications to those users who look for information from particular field or area.

Naviga offers both, easy and advanced full-text searching. It is possible to search by several different criteria such as titles names, publishers names, ISSN, ISBN, key words etc, of course all criteria can be combined at random. Federatively it is possible to search under publisher´s conditions up to allowed level of access. All data are searched at once in quick searching mode which allows cluster for high accessibility attainment and burden distribution.

The standard too of NAVIGA is the customization of service for users and libraries. The user´s profile offers to create own list of preferred titles and to safe individual searching. The institution can adjust the own user interface and incorporate NAVIGA as an integral part of system of own institution.

NAVIGA also offers a service of local administration which includes mainly adding of new sources, registration and activation of new users even for in advance agreed on limited term and setting up access rights of individual users including the level of their access rights. The user fills in a form with basic information required by a library and confirms "license conditions agreement". The request sent by the user will be displayed to administrator who activates new user and send him an e-mail confirmation of his account activation. There is also an option to send an individual or cumulative automatic message to the users.

It is a matter of course to create and provide statistics of number of logged-in users and number of accesses to each source listed by publisher and by titles entered to software in standard format.
