Whether formal or informal, planned or unplanned, most libraries offer some variety of patron training. Call it what you may, when a librarian bends over a public computer and offers help to a puzzled patron, that’s training, too.
Each day, I've used the public computers at the libraries we visit, and at the Madelyn Helling Library, when I attempted to plug in my MP3 player/flash drive, I experienced difficulties fitting it in to the Dell desktop computer's USB port (my computer was named Zeppo). The port was situated at an angle and designed for a smaller device. Try as I may, I couldn't make it work.
