To determine which piece of information might be missing from the bibliographic entry, we need to consider the typical components of a complete bibliographic citation. In general, a complete entry should include:
- A: Author
- B: Date of publication
- C: Title
- D: Page numbers
Since you mentioned pages 7 to 12, it suggests that this might be a part of a book or article, but we cannot determine which specific piece of information is missing without knowing what has already been included in Nick's citation.
However, if Nick is recording information specifically for pages 7 to 12 of "How to Sing Like an Angel" by Josh Grove, it's possible that one of the key components is missing. Often, the title is included prominently, and if he is including page numbers—7 to 12—then perhaps either the author or the date of publication could be missing.
Without any further context or details about what Nick's current entry includes, I cannot definitively identify what is missing, but you can analyze what he has noted based on the structure outlined above. If he already has the title, author, and page numbers but lacks the date of publication, then that would be the missing element.
