Built by record nerds — the kind who flip to the runout groove before the front cover. Gatefold reads the matrix numbers in the deadwax to identify the exact pressing behind every barcode: label, catalog #, country, pressing year vs. original release year, tracklist. No barcode? Search 15 million pressings by hand. Write condition notes like a real store does — light ring wear, small seam split — and flag what is still in the sleeve: insert, poster, obi, hype sticker.

• Barcode queue — pressing-exact matches, server-side, no tab open
• Exact pick — confirm the matrix and runout before you commit
• Condition notes in a collector's own voice, ring wear and all
• 15M pressings — spot a true first press, not just a reissue
• Cover art & tracklist filled in; genre tags added, never removed
