 - title must be a canonical title slug using lower-case words separated by hyphens.
 - Use series_id null and series_index 0 for standalone books.
 - If you use a series_id, series_index must be an integer greater than or equal to 1.
+- Detect omnibus or box-set editions that contain multiple numbered novels, books, or novellas.
+- For an omnibus, make a best-effort range from the filename, tags, and catalog rows. Keep series_index as the
+  first covered book number and include the range in the title when the source title includes it, for example
+  books-1-3.
+- Be careful with omnibuses of novels or novellas later published as one book: keep the omnibus as the audiobook's
+  book record unless catalog rows clearly identify a better match.
 - Do not create publisher collections or author collections as series unless the book metadata clearly gives a
   numbered series.
 - Series belong to authors. Use a series_id only when it belongs to the selected author_id.
