datawebotThriftBooks book data: ISBN, edition, condition & BuyBack
Compare ThriftBooks editions, condition-priced copies and ISBN-based BuyBack offers; keep retail prices separate from account quotes.
A title page can contain several different offers
ThriftBooks is a retailer. A bibliographic work may connect several editions and formats, and each format can have a different condition and price. Keep the edition and offered copy attached to every observation rather than treating the title page as one SKU or one price.

| Record layer | Fields to keep together | Comparison meaning |
|---|---|---|
| Work or title | Displayed title; author/contributor; product page URL | Identifies the book concept, but may join distinct publications or formats. |
| Edition / format | ISBN-10 and ISBN-13; publisher; release date; format/binding; language; page count and physical dimensions when shown | Use edition-level identifiers and format for matching. ISBN does not identify the physical copy. |
| Condition-priced offer | Source offer or item identifier when shown; condition label; copy note; displayed price/currency; availability; capture time | An offer is a condition-specific current retail observation, not a completed sale or durable stock history. |
| Product category | Book, movie/TV, game, music or gift classification | The catalog extends beyond books; do not force non-book items into a book-edition schema. |
Condition is attached to the offered copy
ThriftBooks uses its own condition labels for retail copies. Preserve the exact label and any copy-specific description; do not map these directly to another retailer's grades.

| Displayed condition | How to record it | What it does not establish |
|---|---|---|
| New | Keep the exact condition label with its edition, format and offer | Does not make a different format or ISBN the same item. |
| Like New | Keep separate from other condition offers for the same edition | Not a cross-market standard without an explicit mapping. |
| Very Good | Capture any copy note separately from the grade | The grade alone may not describe every mark or missing insert. |
| Good | Preserve as a source label; retain the source date | Do not assume a fixed condition threshold shared by other booksellers. |
| Acceptable | Associate with the exact offer and edition | Does not establish a sale or a specific defect not stated on the page. |
Compare matching editions and current offer context
For a defensible comparison, match ISBN and format first, then keep condition, currency and observation time alongside the offer. ThriftBooks browse results expose condition and format filters as well as a show-out-of-stock option.

| Comparison step | Keep in the observation | Avoid conflating |
|---|---|---|
| Resolve edition | ISBN-13 and ISBN-10 when displayed; publisher/release date; binding or format | A title match alone can join separate editions. |
| Resolve the copy offer | Exact condition; item note; current price and displayed availability | Different condition offers are not a single price range for a uniform item. |
| Record browse context | Search/query or category; active filters; show-out-of-stock setting; capture time | Search-page range, count or visibility setting is not complete inventory history. |
| Separate the benchmark | Any source-labeled list/reference price and its provenance | A retail ask, BuyBack offer, original list price and completed transaction are distinct measures. |
BuyBack is a separate seller quote and intake workflow
ThriftBooks lets sellers check an ISBN or UPC against current buying needs. That account-linked quote is distinct from all condition-priced retail offers for the book.

| BuyBack step | Current published process | Data boundary |
|---|---|---|
| Check eligibility and offer | Use an ISBN/UPC to see whether ThriftBooks is accepting the item; the public FAQ says offers depend on current market needs and inventory. | The quote is time-sensitive, account/workflow data—not a retail price or public listing field. |
| Prepare the shipment | Accepted items are sent with the ThriftBooks prepaid label in one box no heavier than 40 lb; the FAQ says rejected BuyBacks cannot be shipped back. | Current shipping and eligibility conditions can change; link the current page instead of treating this as a product attribute. |
| Verify and pay | After receipt and content confirmation, payment is processed as ThriftBooks credit or PayPal; current FAQ allows up to 20 business days. | Box/order details, seller contact/payment choice, item acceptance and payout are private workflow records. |
