You say "po-tay-to," I say "po-tah-to": Do you ever get into this type of spat with your search engine? Now, thanks to the Denver Public Library, there are live librarians at your fingertips, via the library's ASK US! 24-hour chat service. All you need is your computer and questions that need answering, and they'll expertly guide you through the process of finding the answers. More than just a standard homework-helper line, ASK US! is a also gateway to databases not available on the web, shared with one-on-one instruction, any time of day or — you know who are — the middle of the night. Sometimes the human touch really does make Internet research easier.
