What are comps?

Comps (comparable listings) are real books listed for sale or recently sold on eBay and AbeBooks that match your book. They’re the foundation of every valuation.

​
What’s collected

For each comp, the system records:
  • Title and condition — How the seller describes it
  • Price — Asking price (active) or sold price (completed)
  • Source — eBay active, eBay sold, or AbeBooks
  • Dust jacket — Whether the listed copy has a DJ
  • First edition — Whether the listed copy is a first
  • Outlier flag — Whether the price is an outlier (too high or low to be representative)

​
Viewing comps

You can see comps in two places:
  1. Book detail — Scroll to the Valuation section
  2. Lexi Chat — “Show me the comps for [book title]”
Comps are displayed as a table sorted by price, with outliers dimmed.

​
Comp limitations

  • Active listings show what sellers ask — not what books sell for. Sold listings are more reliable.
  • Condition descriptions vary wildly between sellers. A “Very Good” on eBay might be “Good” by antiquarian standards.
  • For truly rare books, there may be no comps at all. That’s when Deep Search kicks in.
