Before buying a second-hand book online, check three things separately: whether it is the version you need, whether the actual copy is usable, and what is included in the sale. A familiar cover and a low price do not answer all three.
For a novel you want to read, some cover wear may be acceptable. For a prescribed textbook, the wrong edition can make the purchase useless to you. Start with the job you need the book to do, then ask only for the information missing from the listing.
Is this the edition you need?
Compare the title, author, language, format and edition against your reading list or the publisher's description. Ask for a clear photograph of the actual book's title or copyright page and its ISBN, rather than relying on a stock cover image.
The International ISBN Agency explains that an ISBN identifies a particular title, edition and format. Its assignment guidance distinguishes revised editions and different formats, while an unchanged reprint from the same publisher can retain its ISBN. A later printing date alone therefore does not establish that the content has been revised.
Use that identifier to check the match; do not treat it as a condition grade or evidence that the seller's copy is complete. If the listing's ISBN and the photographed book disagree, resolve that before paying.
For a school or university purchase, use the current prescribed list and ask the teacher, lecturer or course administrator if an older edition is acceptable. Do not decide that solely because the title looks the same. For leisure reading, you may have more flexibility about edition, but still check the language, paperback versus hardback, and whether you are buying one volume or a complete set.
What do you need to see in the photographs?
Ask for photographs of the actual copy, in ordinary light, that answer your specific concern. A long photo shoot is unnecessary if the existing listing already shows what matters.
| Check | Useful evidence | Your decision |
|---|---|---|
| Correct version | Title/copyright page and ISBN; edition and language | Does it match your requirement? |
| Cover and binding | Front, back and spine; any split or loose section shown gently | Is the wear cosmetic, or does it affect handling? |
| Pages | Page edges and an example of any staining, highlighting or damage | Can you comfortably use this copy? |
| Completeness | Seller confirmation about missing or loose pages, inserts and volumes | Is everything you need included? |
| Workbook use | Example of completed exercises, with personal details covered | Do you need blank answers or is a used copy suitable? |
Photos cannot prove that every page is present or that a book has no smell. Ask directly about missing pages, water damage and odour if these would change your decision. Do not ask a seller to force the spine flat, damage the book or send scans of whole chapters. A small, relevant condition example is enough to ask for.
Names, phone numbers or school details written inside a used book are not useful buying evidence. Ask the seller to cover those details in photographs.
Separate wear you can accept from problems you cannot
Write down your non-negotiable requirement before comparing prices. For example: “I need this exact edition with readable text; a creased cover is fine, but completed exercises are not.”
“Good condition” means different things to different people. Replace that label with concrete questions: Are any pages loose or missing? Is there writing throughout or only a name inside the cover? Does highlighting obscure text or diagrams? Are there tears across anything I need to read?
For an ordinary reading copy, decide whether the disclosed wear interferes with reading and handling. If the attraction is a claimed signature, rare edition or collector value, this checklist is not authentication or a valuation. Seek suitably qualified advice before paying a premium for that claim.
Does a textbook include usable online access?
A printed book and access to an online learning product are separate things to verify. Ask which digital product, if any, is included, whether its code has been used, and whether the publisher permits the access you need for that edition and region. Do not ask for the code itself in a public photo or for the seller's account password.
Publisher rules are product-specific. For example, Pearson's Australian Reader+ second-hand-book guide describes a reactivation purchase for an already activated book code. That is an example of why to check, not a South African price, a rule for every Pearson product, or a promise that reactivation is available for your book.
If online access is required for your course and its availability or cost is still unknown, the purchase is not ready to compare. Confirm those details with the relevant publisher or course provider first. Do not assume that “code included” means usable access.

Fill this in for each serious option. Leave an unknown as “not confirmed” rather than treating it as a yes.
- My purpose: leisure reading / prescribed study / another specific use.
- Required version: title, author, language, edition, format and ISBN where applicable.
- Actual-copy evidence: photographs checked; missing pages, writing and damage confirmed.
- What is included: one book or named volumes; inserts; separately verified digital access if needed.
- Total I will pay: item price plus delivery and any other confirmed required costs.
- Decision: buy / ask one remaining question / pass, and why.
For a simple comparison, imagine two copies of your prescribed edition: one has completed exercises, and the other has a worn cover but blank exercises. If blank exercises are essential to you, the cheaper completed copy is not an equivalent option. This is an illustrative decision, not a tested listing or a claim about current prices.
For the arithmetic, use our guide to comparing an item's price with delivery and other costs. It uses clothing examples, but the same addition helps avoid comparing a delivered book with a collection-only price. Confirm the actual delivery arrangement and applicable terms before paying; do not rely on a possible return to solve a known mismatch.
