I have been reluctant to write about metatopics. It is already extensively discussed by Do Mi Stauber, Janet Perlman, and Margie Towery in their books, as well as, I assume, elsewhere. Appropriately handling the metatopic is also one of the trickier aspects of indexing to master. I am not sure what I can add to the discussion that is new. I also suspect that reading about the metatopic only goes so far. The best learning comes from taking theory and applying it to real books, though perhaps that is simply how I learn best.

Still, I was recently talking with a new indexer who was struggling with the metatopic, and a misconception came to light that might be worth highlighting. Specifically, this new indexer was feeling overwhelmed by the multiple metatopics which she had identified in the book. The misconception was that the metatopics identified were actually main topics, or what Margie Towery might call supermain headings. These are clearly important topics that need to be in the index, but they do not encompass the whole book, which is what differentiates main topics from metatopics.

I like what Janet Perlman says about the metatopic in her book, Indexing Tactics & Tidbits (Information Today, Inc., 2016):

“…The metatopic is intertwined with aboutness. When the indexer can make a cogent statement of what a book is about, whether it be a word, a phrase, or a sentence, he has identified the metatopic of the book.”

There is usually only one metatopic in a book, sometimes two if a book has dual subjects. It may be a complicated metatopic, requiring a sentence or three to explain, but it should still be a single topic or concept that encompasses the whole book.

Correctly identifying the metatopic is important because this impacts how the metatopic is handled in the index and how the whole index is structured. This new indexer was having trouble because she was trying to follow the advice to disperse information away from the metatopic entry. This is generally good advice, and the reasoning is, since everything in the book, theoretically, falls under the metatopic, all main topics should stand on their own as main entries. In this approach, the metatopic should be a signpost to the main entries via cross-references, and should only gather general information that are not able to stand alone. It is usually not a large entry. This approach works fine when there is a single metatopic, but not if you are trying to disperse information for multiple topics. As this indexer learned, if you are trying to disperse all of the information from all of the main topics, the index quickly loses all sense of structure and some information simply does not stand alone very well. 

The flip side to dispersal is gathering, and while gathering the whole book under the metatopic entry is not practical, gathering under individual main topics is. This is why we need to distinguish between the metatopic and supermain headings, because these different types of information and entries are handled differently. As I have discussed previously, entries should contain or direct readers to everything they need to know about that topic. Overly large entries can be split up into smaller chunks that are still meaningful, but we should see dispersal and gathering as complementary techniques for structuring the index. They each have their role, and the starting point is correctly identifying the different components of the book and how those components translate into the index.

The metatopic plays key role in the index, but only if it is first correctly identified.
