●Recent developments in ICT have enabled libraries to publish their catalogs on the Web making them accessible locally (on site) and/or remotely through the Web as a Web OPAC.
●OPACs can also be linked to the circulation module so that users can find out from its OPAC record the status of an item (whether it is on loan, on-shelf, etc.) and loan information about it, as well as making a self-reservation and/or self-check-in/check-out (and maybe other features such as ILL, and links to electronic resources on the Web or local databases)
