Some electronic resources purchased by the library have intrinsic access restrictions.
In the case of CD-ROMs, the cost may be prohibitive for us to offer the information via a network. In the case of databases offered via the Internet, some contracts dictate who can use the resource. Limitations may include a set number of simultaneous users or even a certain subset of the UT Austin community. When creating assignments, consider the number of people in your class and the accessibility of the resources you are suggesting they search. If your class is fairly large, you may wish to suggest resources that are widely available.
