title: How we use other sites description: Trade portals are radar. Primaries are the shelf. No paywall mirror. tags:
- guide
This archive is not a newsletter, not a handbook shop, and not a competitor to trade portals. It is a labeled public shelf.
Graphene-Info and cousins
Graphene-Info (Metalgrass, since 2009) is the widest public radar for company names, SKU talk, and “this week” releases. OLED-Info and the rest of that network work the same way.
Allowed
- A name we did not have (plant, product mark, listing).
- A date that points at an ASX / AIM / SEDAR / Companies House / company PDF.
- A company-stated tonne or m² figure, logged as company-stated or Preliminary, with the year of the copy.
Not allowed
- Pasting their handbook, market-report tables, or catalog blurbs.
- Treating their paraphrase as the primary.
- A paywalled sentence reconstructed from memory.
If Graphene-Info is the only place a number appears, the row stays Preliminary until the PDF exists here. If their story and the filing disagree, the filing wins and we note the mismatch.
Same rule for IDTechEx slides, broker notes, and AI roundups. how-we-log-figures · unsourced
