Due to licensing agreements, access to most Library databases and other electronic resources, such as electronic journals, is restricted to computers on the University of Delaware campus. If you are a current University of Delaware student, faculty, and staff using an Internet service provider such as Verizon or Comcast to access the Library’s Web site, you might encounter links to licensed resources from the Library’s Web pages. The first time you click on such a link, you will be taken to the University of Delaware proxy page. After you enter your UDelNet ID and password, you will be authenticated as a University of Delaware user and will continue to your selected link. You generally need to do this only once during your session at the Library’s Web site.
With proxy access, you can use all Web-based Library databases and electronic journals just as if you were on campus. You can access all Library electronic resources from computers at any off-campus location—home, office, another university, public library, etc.
If you are a frequent user of licensed Library resources, and use Firefox, Opera, Safari, and other browsers to access the Library’s Web site, you are encouraged to install the “UD Proxify” button on your toolbar using the instructions linked on Using UD’s Web Proxy Server. On rare occasions using Library electronic resources you will need to reestablish proxy access. This might happen, for example, when you leave a licensed resource, go somewhere else on the Web, and then return to the Library’s Web site. In addition, some databases and e-journals require that you reestablish proxy access after you have logged on to them. By installing the UD Proxify button on your toolbar, you can quickly get to the proxy sign-in page again. You need to install the UD Proxify button only once; installation is easy.
If the URL in the address box of your browser begins with http://proxy.nss.udel.edu: you have proxy access to licensed resources.
If you are on a computer at the University of Delaware or dialing directly into the University, you do not need to use the proxy server. If your computer has an IP in one of the ranges below, then you will have access to Library resources, and you do not need the proxy server.
University of Delaware IP Ranges:
Access to DELCAT, the online catalog of the University of Delaware Library, is open to all.
In order to “unproxify” a URL to determine the actual URL so that you can include it in a citation, go to the main proxy page and enter the proxied URL (beginning with http://proxy.nss.udel.edu:) in the “Unproxify” search box.
Due to license restrictions, Library users not affiliated with the University of Delaware are not allowed remote access to licensed Library resources. You may use these electronic resources, but only in the Library.
