A student gets an automatic explanation and compares it with library materials. I propose to use this activity to understand differences between texts, editions and levels of in-depth study.
In the example, a source clarifies a limit that the answer had omitted. The library should not be presented as a nostalgic alternative to technology.
It can offer useful documents and skills to verify it. The educational value lies in the transition from a received response to information sought, read and discussed.
