Connexion
Find support materials about Connexion browser and Connexion client.
There are two interfaces to access the power of Connexion: a Web browser-based interface and a Windows® desktop application. Within the Web browser-based interface, you can choose between the full Cataloging interface or the easy-to-use Express interface. Which interface you use depends on the unique needs of your library and cataloging staff. See a comparison chart to compare functionality in both interfaces.
