If you had stated the relevant schema, including that of whatever table(s) contain the tag values and/or association with the author_title_body table, somebody might volunteer a query. You might also peruse the [SELECT documentation](https://sqlite.org/lang_select.html) where it mentions, in section 1, the effects of the join clause. This would help you understand why a single-table query (of a table without any tag columns) does not reveal anything about tags.
