It would be a good enhancement for Lists to have an Expiration date option, much in the same way that Pages and News items do.
Agreed: An expiration date would allow public lists to disappear from the OPAC after they're not relevant anymore. For example, a list tied to a holiday or library event. A "published date" would allow the user to plan when a list would appear.
