Online Demo
You can view Opac Online at your leisure on our demo site.
The demo site uses an indexed Adlib catalogue containing over 100.000 records and a thesaurus of about 10.000 keywords.
Opac Online is situated in the content pane (the middle part) of the demo site. The sections to the left, to the top and to the right of it are not part of the Opac Online application. This is to illustrate including Opac Online in another (your!) web site.
The contents of the titles and abstracts in the catalogue is randomly put together from English texts in the public domain, such as the works of Shakespeare and Darwin. Authors were randomly assigned using a list of authors we have found on the internet; the keywords were assigned in like manner.
The Japanese version is machine-translated from the English, so do not expect correct Japanese. This version is purely an illustration of the possibility to display the application in non-Western languages.
