I’ve found that it’s not uncommon for an interested individual to find details that have not been documented or “found” by others. I collect video games and have found variants of popular games that have been otherwise undocumented on any list or archive that I was aware of. I’ve found audio recordings from the 90s that seemingly have no recorded history on the internet.
These aren’t things historians have had hundreds of years to document, but several thousand or more people have been on this space long before I was looking at it more intently than I could ever and I still come across things from time to time that weren’t known to exist.
Likewise, in the past month I’ve spent an unfortunate amount of time reading laws and board bylaws and it doesn’t take long to find long forgotten rules that are being actively violated. Even outside of code, documentation is hard.
Tyler Cowen recently interviewed a historian (Alan Taylor), and they approached this subject near the end of the episode—how much the job of a historian still involves browsing undigitized material sitting on a shelf in a cold room somewhere. Around 3215 seconds* in:

* of the audio version, that is; at that timestamp in the YouTube video, they're discussing the question "How will large language models change historical research"—interviewee's response: he doesn't know
This happens often when going down the rabbit hole on a niche project. For example, repair and restoration of Persian rugs.
There are many details to the craft that are hinted at in variety of formats, (youtube videos, blog entries, etc) but the clear truths are not clearly stated anywhere. These are stored in the minds and practices of artisans.
Try skimming the Wikipedia articles on some major authors of that era, to get a sense for how much short (or serialized) fiction & poetry was routinely published in newspapers and magazines back then.
Without some specific clues, a real historian would not be looking for Bram Stoker stories in an 1890 issue of the Daily Express Dublin Edition. He'd be skimming through the archives of many of the newspapers & magazines published in an era and geographic region, cataloging authors & stories & poems. "Success" would be just compiling a well-done catalog. 15 minutes of fame in the popular press could equally well result from finding some unknown early work by James Joyce, or Winston Churchill, or George Bernard Shaw, or Oscar Wilde, or Yeats, or ...
