SCAN, for example, can be used to find a list member. Listy responds accordingly. Listy doesn't mind which case you use in command lines. They are an invaluable source of data collected over the last several years. Each separate lists in the system has its own archive, including the state lists.
Data is searchable by author, topic or words used.
It really is a fantastic system, and was carefully crafted by the lists founder, John Roraback, to be the core professional element of the list system. The first time you access the archive, you will be asked to enter your name and assigned password to verify that you are an approved member of the list system. If not, you will have to enter this information each time to ensure that only authorized members have access to the data base. Try the archives. Test the data base and discover what it can do for you, before you need it.
