County recorder vs. county assessor — they sound the same, they're not
If you've ever Googled property records and gotten confused by '/recorder/' showing one set of data and '/assessor/' showing a different set — you're not alone. They're two distinct offices doing two distinct jobs.

The recorder
The county recorder (or registrar of deeds, or clerk-recorder, depending on the state) is the legal-document archive: deeds, mortgages, liens, satisfactions, judgments, easements, releases.
When something is 'recorded' against a property, that creates the public legal trail of ownership + encumbrances. Title companies live in this data.
Most counties publish recorder records online; some still require in-person searches at the courthouse.
The assessor
The county assessor (or appraisal district in TX) determines a property's assessed value for tax purposes — separate from market value, separate from purchase price.
Assessor data: parcel ID, owner of record, mailing address, square footage, year built, assessment history, exemption status (homestead, senior, veteran).
Tax bills are calculated from assessment × millage rate (per the property-tax-millage article in this library).
Why the distinction matters
An out-of-date recorder record can mean a deed transfer hasn't been processed yet (months of lag are common in busy counties). An assessor still showing the prior owner is normal for the year of sale; expect reassessment + re-billing the next cycle.
If your recorder shows the deed transferred but your assessor shows you don't own it yet, it's almost always a timing issue, not a problem — wait one cycle and re-check.
If your assessor adds a homestead exemption but your recorder shows no homestead designation — that's also normal. Homestead is administrative (apply with the assessor), not recorded against the deed in most states.
Where data quality differs
Recorder records are legally authoritative — the recorded deed is the deed.
Assessor records are administratively authoritative — the assessment determines the tax bill, but it's not a legal title document.
If the assessor and recorder show conflicting owners, the recorder wins legally (you need to file a deed correction with the recorder; the assessor will follow).
