The five rulebooks
Marginalia pulls from these federal sources and weaves them together. Tap any one to see which everyday topics it shows up in.
Code of Federal Regulations
The federal government's giant rulebook — everything from food labels to airline safety.
Internal Revenue Manual
How the IRS actually does its job, in their own words.
Treasury Financial Manual
Rules for how federal money gets spent, tracked, and reported.
Uniform Commercial Code
The shared playbook every state uses for sales, leases, and contracts.
Federal Trade Commission
Watches over fair competition and protects consumers from shady practices.
Sources we want on the shelf next.
Marginalia is built one rulebook at a time. Here's what's queued — these aren't live yet, but the room is reserved.
State constitutions & codes
All 50 state constitutions plus the full statutory code of every state — searchable next to the federal sources you already have.
Federal caselaw
Supreme Court, circuit, and district opinions wired into the statutes and regulations they interpret.
Federal Register, demystified
Daily proposed and final rules, threaded into the CFR sections they touch — so you can see what's about to change before it does.
Local rules & municipal codes
The county and city ordinances that actually govern day-to-day life — landlord-tenant, parking, zoning, noise — pulled into the same index.
Agency guidance & opinion letters
The unofficial-but-binding stuff: DOL opinion letters, IRS revenue rulings, FTC guidance — usually buried, finally indexed.
