| Abstract: | Since the development of the Online Public Access Catalogues in the 1970s, libraries in Europe and America have devoted more and more attention to it. To date, it has already developed to the third generation. The OPAC System makes those users who lack training and experience be able to use it directly. It provides the users a kind of capability to access, which is neither like the order language with a very complex function, nor is it like the "menu" one with a very simple function. The interface design of it is an important phase of OPAC device,the study of which falls into the following categories;1)the matching aid.2)the retrieval aid.and 3)the semantic/contextual aid.The successful practice of the development and services of OPAC opens up a wide range of prospect for readers to use library materials directly. |
