Books stores, sorts, and searches a "virtual card catalog" for a personal library. It makes it simple to enter new books, edit the information of older books, and sort the books by attributes such as title and author. Books also includes built-in searching for quick book information retrieval, and XML support for importing and exporting collection information in HTML and XML.
AddressBook X LDAP provides a shared addressbook on your local network, without the burden of subscriptions. It is an iSync enabled application which transfers contacts from the AddressBook to a central LDAP directory. It also provides the ability to browse and search the directory. Multiple schema mappings are available and can be customized and extended to address individual needs. Currently, ABxLDAP Person (an extension to InetOrgPerson) is fully supported, but the Mozilla Schema and the basic InetOrgPerson are in development. Support for Active Directory is included as well.
