OPAC

                          On-Line Public Access Catalogue
The OPAC provides three levels of searching to the user; Simple, Easy and Expert. The OPAC can also act as the main front-end menu for other databases and applications, such as networked CD-ROMs, the Internet etc.
                          Search Options
Simple Search – Uses relevance ranking, eliminating the common failed search problems such as ‘no hits found’ or ‘too many hits found’

Easy Search – Users can search for text in all fields or limit searches to selected fields.

Expert Search – Offers all searching features, including relevance ranking and Boolean operators. Searches can also be limited to specific types of material and browsing facilities are available.
                          Dynamic Hypertext Navigation
Users can navigate around the database using a hypertext-like system, moving forward, branching and re-tracing their steps at will. A user can select words in a record and use them to continue to search through the database. C2 provides the user with a completely dynamic ability to select search terms, moving beyond the pre-defined ‘green’ hyperlinks commonly used for searching static CD-ROM databases.
                          Search Types
Retrieved records are automatically ranked according to their relevance to the user’s request. Records that are highly relevant are ranked first, followed by records that are less relevant. Since the most relevant records appear at the top of the list, users do not need to look through long lists to find records of interest.
                          Multilingual Navigation
Basic search navigation, button labels and other screen information can be set up in any language. Patrons and staff can specify which language to run C2 in at any time.
                          User Information
Users are able to view the circulation status and order status of all materials. They can view their own details, status and borrowings. Borrowers can place their own reservations from the OPAC screen. Comments and suggestions can be sent to library staff. Users can print individual bibliographies.
