Wherever your ideas comes from, be it image, fact, lie, it is interesting to have some type of documentation surrounding those ideas. Maybe there is a biographical link, a creative link, an environmental link, a detail that someone, somewhere, sometime will pick up about your piece. Because the original ideas are oftentimes NOT the core of a story or poem, they can add a certain depth for the serious reader. Having the ability to “uncover” these gems can be very rewarding to the parsers. To others, this type of backstory doesn’t matter. That’s great. Writing should be for different audiences. But giving the hardcore fans, the historical sleuths, the biographers of the future something to discover can be satisfying.
Writing can be a jigsaw puzzle. Although the endgame is a complete image/narrative, the process, the construction, the genesis is mostly lost to readers. Just imaging the exhilaration of finding a little piece of the puzzler inside the puzzle — a tidbit, a factoid, a revelation. This can elevate the serious reader to another level.
Biographical content is not necessarily the key. “Write what you know” can be the worst advice a writer could attempt to follow. This said, if there is a cool detail that lead to your piece, a detail that you can jot down somewhere in a journal, kept safe for future discovery, that is a priceless nugget. Even if it is totally unnecessary for the final fiction, that nugget can add so much to someone who had taken the time to discover it.
With practice, and by following your personal voice, style, aesthetic, these nuggets will start to manifest in the overarch of your oeuvre: links, parallels, juxtapositions that alone mean nothing; bits that taken together, maybe with the addition of extra-textual notes, become beacons of meaning.
That’s why it is important to save your notebooks, to have someone who knows about them, someone who will, eventually, help the world decipher the hidden stories within your stories.
