## Where to find the information

This will best be found by watching or listening to the content of the item; it may also be discernible from the item and its packaging, but this may not always give a full picture of what the item is about.

For the same reason, it will usually be necessary to watch/listen to at least a reasonable sample of the content to have an accurate sense of the subject matter. Referring to Library of Congress and/or MeSH subject headings may help.
