How Spectrum works
Spectrum is a maintained guide. It tries to make useful information easier to find without turning inclusion into endorsement.
Listings
Listings are checked against public sources and carry a verification date. A listing can appear in more than one category or discipline when it genuinely fits both. When a source no longer supports a claim, the listing should be corrected, expired or removed.
Independence
Being listed does not mean Spectrum endorses, accredits or ranks an organisation. There is no paid placement.
Guides
Spectrum separates general factual guidance, variable or source-specific requirements, verified York information and attributed expert opinion. Current rules from the organisation involved override generic conventions.
Interviews
Interviews and expert notes are attributed. An expert's experience can improve the guide without becoming a universal Spectrum rule. Declining an interview does not affect directory inclusion.
Corrections
If a listing or guide claim is wrong or out of date, send the current source. Better evidence should change the record.
