Source used books in bulk — by the thousand, by ISBN

Upload a list of ISBNs and target prices. BIBLIO matches them against tens of millions of used, rare, and out-of-print titles from thousands of independent booksellers. Then auto-purchases within your budget or sends the matches back for your approval.

How it works

1. Send us your list. ISBNs, quantities, target prices, and condition requirements: a spreadsheet, a CSV, or an API feed. No list is too long.
2. We source and match. Your list runs against BIBLIO's full marketplace: millions of used, rare, and out-of-print titles from thousands of vetted sellers worldwide, including the long-tail and OP titles big wholesalers can't supply.
3. You choose how to buy.
   • Auto-purchase: We automatically buy every title that meets your target price within your set price tolerance, so minor fluctuations don't stall the order.
   • Review & approve: We return matched results with live pricing; you accept what you want before anything is purchased.
4. One order, one invoice. We consolidate fulfillment and billing across hundreds of sellers into a single, trackable order.

Two ways to buy

Auto-purchase: Set it and forget it.

Hand us your list and your budget. We purchase anything at or under your target price the moment it's available, with a tolerance band you control (e.g., "buy up to 5% over target"). Ideal for large, ongoing, or time-sensitive sourcing.

Review & approve: Stay in control.

Prefer a human checkpoint? We return a priced, matched manifest. You approve line by line or in bulk, and we purchase only what you greenlight. Ideal for first orders, fixed budgets, and procurement sign-off.

Who it's for

• Libraries & archives: Collection development, replacement copies, and hard-to-find out-of-print titles, matched to your exact ISBNs and condition standards.
• Schools & universities: Course adoptions, departmental orders, and reading lists fulfilled in volume, on budget.
• Booksellers & retailers: Wholesale inventory sourcing across categories, with the margins that come from buying direct from the marketplace.
• Institutions & nonprofits: Literacy programs, community and prison libraries, and large donations, sourced affordably at scale. 

Why BIBLIO

• The catalog wholesalers don't have. Over 100 million used, rare, and out-of-print titles, not just current in-print stock.
• A real seller network. Thousands of independent booksellers worldwide means depth on long-tail and OP titles, and competition that keeps prices down.
• You set the price. Your targets, your tolerance. No opaque wholesale markup.
• Built for volume. Lists of thousands of ISBNs, deduplication, alternate-edition matching, partial-fulfillment handling, and condition filtering.
• One point of contact. A dedicated sourcing team, consolidated invoicing, and order tracking from list to delivery.
