OPAC employs a service called Alert. The function of this service is to memorize search conditions and send notification by e-mail, RSS, etc. when the library receives any matching material.
After a search with OPAC Bib Search, you can register the search conditions by clicking "Add Search Alert." You can also register search conditions from Alert in OPAC.
The process of registration displays the Alert list screen. From there, you can check the list being sent and change the sending frequency.
You can register an RSS reader from the [RSS] button. Once you have registered the RSS reader, you can check for any new arrivals of the relevant materials, even without checking OPAC.
