The Citation Aggregator plugin aggregates links from
Delicious,
Connotea and
Google Reader websites and stores them inside the WordPress System. The plugin allows you to add categories to the aggregated links and also manually group links together using additional categories.
The websites are checked for new links approximately one every hour. The list of aggregated links are used to create an RSS feed, containing the most recent 10 links, and posts and pages containing lists of links using shortcodes.
The plugin is being used to help build a community at the
Libraries Interact website.
Extract the zip file and just drop the contents in the wp-content/plugins/ directory of your WordPress installation and then activate the Plugin from Plugins page.
Once Activated use the settings page of the plugin to configure the plugin including specifying the tags to aggregate, the users to allow, and the services to use.
