I will be interviewing for a cataloging position next week for public library. On the information sheet, it wanted candidates to be familiar with the program Innovative Millenium. The library I work at uses Polaris, and the academic library I am at for my internship uses Sirsi. There are some tutorials available online, but it's one thing to read about a product and another thing to use it. It doesn't look like it's for sale for individual users. My question is how do I go about becoming familiar with Millenium before the interview? Has anyone here used it for cataloging?

Thanks for your help!
