Topic Pages - Library Catalogs

Credo can add your library catalog as a resource on Topic Pages if your catalog has a Z39.50 server. Another option for adding your library catalog is available through WorldCat.

We will need the following information to begin the setup process:

  1. Z39.50 server name and port location  (example: voyager.university.edu: 210)
  2. Database code  (If this catalog is shared by many libraries, please send us the database code that would limit to your library's holdings only.)

Please send the information above to  This e-mail address is being protected from spambots. You need JavaScript enabled to view it. .

If the library catalog has a firewall, you will need to permit access to these IPs so that we could include the catalog results in Credo Topic Pages:

64.206.31.250
174.143.173.177
