I argue that for most of the cases the real use of the materials will not be longer than 3 days. With today's technology, CDs and DVDs can easily be imported onto personal computer libraries under certain copyright restrictions. Music can definitely be imported while for DVDs, there are scarcely any cases when the users need to watch it for more than 3 days. What happened under the policy is that users borrow and keep the materials much longer than they need it. Then because there are 7 days recall delay, many times people don't return until the last day, not because of real need but simply due to the deadline. For other users who need the material, especially digital materials, it is first of all frustrated to find most of the CDs or DVDs are checked out and then even more so when everything they want they will need to wait 7 days.
My friend at UIC tell me that their library require CD/DVD be returned in 3 days. She described very pleasant experiences of being able to get the materials she want immediately most of the time or in 3 days to the most. I argue that by adopting the suggestion I've made, the library will be able to serve more people's need WITHOUT decreasing the quality in the majority of cases.
Generally, our colleagues at Circulation report that most patrons enjoy being able to borrow CDs/DVDs for long periods. Admittedly, there are certainly some recreational users who borrow a DVD, but then don't watch and return it promptly, which inconveniences other users. However, patrons using the CD/DVD for scholarly research often need to keep the media longer than a few days. Music students writing papers, for example, often need to listen to a CD repeatedly over the course of several weeks.
From a technical standpoint, it's very easy to rip music and video to a personal computer. However, from a legal perspective we can't require (or even encourage) this practice, anymore than we can encourage patrons to photocopy entire books. In cases where multiple people need to use a CD, such as for a class, we will put the disc on course reserve and/or look into ways to legally stream the music temporarily.
