How We Verify Listings
A card show is only useful if the date, the venue, and the door are right. Here is what happens to a listing before it reaches the site — and what keeps happening after.
Every show is reviewed before it's listed
Nothing publishes automatically. New events — whether a promoter submits one or it comes from a public show calendar — land in a review queue, where a person checks them: that the show is real and has a firm date, that the venue and city agree, and that there is enough detail for a collector to actually turn up. A listing that clears review goes live. One that doesn't stays in the queue until the missing piece is confirmed, rather than going out half-finished.
Duplicates are detected and merged
A recurring show can reach us from several directions at once — the promoter submits it, and it also appears on a public show calendar under a slightly different name. Before anything publishes, it is compared against every event already in the directory on name, date, venue, and address together, not on the name alone. That is deliberate: "Front Row Card Show — Portland" and "Front Row Card Show (Portland, OR)" on the same date at the same building are one show, and the directory treats them as one. Matches are merged into the existing listing instead of being published beside it.
Venue names are reconciled against our venue registry
The venue is the part of a listing people actually navigate by, and the same building reaches us spelled several ways — "Middleburg Heights Community Center" and "Middleburg Hts Community Center" are one hall. Venue names are matched against a registry built from the shows already in the directory, so the variants collapse to a single venue with one page rather than scattering across near-duplicates. Where a venue field turned out to hold a show name instead of a building, the correction is recorded by hand in a maintained list of overrides and applied from then on.
A listing that names no venue at all is not published: it is held rather than filled in with the show's own title, because a show name sitting in the venue field looks like data but tells you nothing about where to park.
Listings are corrected continuously
Review doesn't stop at publication. Venues get renamed, promoters move a show across town, a title gets truncated somewhere upstream. Where a listing came from a public calendar, that calendar is re-read on a schedule; when it now disagrees with what we hold, the difference is raised as a proposed change for a person to accept or reject, never written straight over the live listing. Accepted corrections flow through to the descriptions and structured data that search engines read. Shows drop out of the index automatically once their date has passed, so what you're browsing is what you can still attend.
Some things stay unresolved — a show with no venue named anywhere, a listing whose original page has gone dark. Those are held rather than guessed at, and they get picked up again when better information appears.
Promoters can claim and manage their shows
The person running the show is the best source there is. A free promoter account lets you claim your listings and manage them directly — correct a venue, update times and table counts, add a flyer, and keep future dates current as you schedule them. Claimed shows carry the promoter's own details, which is the shortest path between a correction and the live page. If your show isn't listed yet, submit it for free.
Found something wrong?
Corrections are welcome and they go through the same review process as everything else. Email cardshowhub@gmail.com or use the contact form with the show name and date, and we'll take a look.
