Buying and Selling Preloved Children’s Books
Children’s books can often be enjoyed by several families, making them well suited to buying and selling preloved.
Condition and completeness matter. Missing pages, torn flaps, mould, writing, damaged bindings and incomplete activity sets can affect whether a book is suitable for continued use.
This guide explains what buyers and sellers should check before children’s books are listed, purchased, bundled, collected, posted or used.
How to Use This Guide
This is general information and signposting for UK families who are comparing children’s products. Kidora is not a product-testing, medical, legal or safety-certification service. The guidance does not approve any individual item, guarantee a safe purchase or replace manufacturer instructions, official recall notices or advice from a suitably qualified professional.
Product requirements, safety notices and marketplace features may change. Use the linked original UK sources for current guidance, and check the manufacturer’s information for the exact product model before deciding whether an item is suitable for reuse.

Identify the Exact Book
Before buying or selling, check:
- Title
- Author
- Illustrator where relevant
- Publisher
- ISBN
- Edition
- Format
- Language
The ISBN usually appears on the copyright page or back cover.
Check the Format
Children’s books may be:
- Board books
- Paperbacks
- Hardbacks
- Lift-the-flap books
- Touch-and-feel books
- Pop-up books
- Sound books
- Activity books
- Boxed sets
State the format clearly because condition expectations and postage costs can differ.
Check Age and Reading Suitability
Age recommendations can help families narrow a search, but they do not set a reading deadline for every child. BookTrust’s family reading resources offer additional ideas for choosing books children may enjoy.
Consider:
- Suggested age range
- Reading level
- Book length
- Amount of text
- Subject matter
- Small detachable parts
- Interactive features
Age guidance is only a general indication. Children develop reading interests and abilities at different rates.
Inspect Every Page
For an ordinary picture book, a folded corner may be mainly cosmetic; for a workbook or interactive title, a missing page may remove an essential activity. State the extent of any writing or damage rather than hiding it within an overall condition label.
Check for:
- Missing pages
- Tears
- Folded corners
- Loose pages
- Water damage
- Food marks
- Writing or colouring
- Stickers
Do not rely on the cover alone when judging condition.
Check the Binding
Inspect:
- Spine
- Glue
- Stitching
- Hinges
- Cover attachment
State clearly when pages are loose or the spine is cracked.
Check Board Books
Look for:
- Chewed corners
- Peeling surfaces
- Swollen pages
- Split edges
- Wipe-clean damage
Books with heavy chewing, contamination or mould may be unsuitable to pass on.
Check Lift-the-Flap and Pop-Up Books
Confirm that:
- Every flap is present
- Pop-up sections open correctly
- Pull tabs work
- No mechanism is torn
- Detached pieces are disclosed
Check Touch-and-Feel Books
Inspect interactive materials for:
- Missing sections
- Peeling
- Contamination
- Loose fibres
- Damage from cleaning
Check Sound and Electronic Books
Electronic books bring extra risks, including insecure battery compartments. The Child Accident Prevention Trust battery-safety guidance explains why suspected battery swallowing is an emergency; check the complete original source for current action.
Sound books, light-up books and interactive learning books should be treated as electronic products as well as books.
Check:
- Buttons and switches
- Battery compartment
- Every screw or fixing
- Volume, lights and sound
- Missing battery cover
- Corrosion, swelling or heat damage
- Whether the exact product has been recalled
Do not sell or use a sound book with an insecure battery compartment, loose battery or exposed wiring.
If a child may have swallowed a button battery, go straight to A&E or call an ambulance. Do not wait for symptoms. See current button-battery safety guidance.
Check Activity Books
Activity books may have limited resale value when pages have already been completed.
State:
- How many pages are unused
- Whether stickers remain
- Whether pens or accessories are included
- Whether answers have been written in
Check Boxed Sets
Confirm:
- Number of books
- Exact titles
- Box condition
- Missing volumes
- Any duplicate books
If an original boxed set had six books but the listing contains five, make the missing title explicit. Buyers can then decide whether the remaining collection meets their needs.
Do not describe a set as complete unless every expected book is present.
Check Series Carefully
For series, include:
- Series name
- Book numbers
- Titles
- Missing volumes
- Edition differences
Readers may care about publication order, edition, large-print or audiobook compatibility. A photograph of book spines and an itemised list can prevent confusion.
A mixed-edition series may still be useful, but it should be described accurately.
Check for Mould and Damp
Inspect:
- Page edges
- Inside covers
- Spine
- Boxed-set cases
- Books stored in lofts, sheds or garages
Do not sell or donate books affected by mould, serious damp or persistent musty contamination.
Check for Pests
Before passing on stored books, inspect for:
- Insect damage
- Droppings
- Eggs or larvae
- Chewed edges
Remove Personal Information
Remove or cover:
- Child’s full name
- School labels
- Address labels
- Personal notes
Do not damage the book unnecessarily when removing labels.
Leave Useful Ownership Notes Visible Where Appropriate
A simple first name or gift inscription may be acceptable when it does not reveal sensitive information.
Disclose inscriptions in the listing if they are prominent.
Clean Books Carefully
Cleaning methods depend on the material.
General steps may include:
- Dusting covers
- Wiping laminated surfaces lightly
- Using a soft dry cloth
- Drying fully before storage
Do not soak books or use harsh chemicals that may damage print, glue or interactive elements.
Buying Children’s Books Online

- Is there water damage or mould?
- What edition is it?
- Does the sound function work?
Buying Book Bundles
A mixed-age bundle may still be useful if the exact titles and formats are visible. Families seeking other low-cost reading options can check their local library service as well as preloved listings.
Bundles can provide good value when:
- Books suit a similar age range
- The buyer wants most of the titles
- Condition is shown clearly
- The bundle price is lower than buying individually
- Postage remains reasonable
Create Useful Book Bundles
Useful bundle types include:

Selling Children’s Books
A useful listing should include:
- Title
- Author
- ISBN or edition where relevant
- Format
- Condition
- Missing pages or parts
- Writing or inscriptions
- Exact bundle contents
- Delivery or collection details
Use Kidora’s Correct Condition Labels
Kidora currently uses:
- New
- Like New
- Very Good
- Good
- Well Used
Select the closest condition and describe creases, writing, worn corners, loose pages, missing flaps and box damage separately.
Photograph Books Clearly
Include photographs of:
- Front cover
- Back cover
- Spine
- Copyright or ISBN page
- Representative inside pages
- Writing or inscriptions
- Damage
- Interactive features
Photograph Sets and Bundles
For a bundle:
- Show every front cover
- List every title
- Photograph the complete group
- Show the box or case
- Separate damaged books
- State when editions differ
Do Not Hide Damaged Books in a Bundle
Every book in the bundle should be visible or listed clearly.
Do not use one attractive top book to conceal heavily damaged or unwanted books underneath.
Pricing Children’s Books
Consider:
- Current retail price
- Condition
- Edition
- Completeness
- Demand
- Whether it is out of print
- Comparable UK listings
- Postage cost
Everyday books usually need modest pricing unless they are unused, collectible, complete sets or difficult to find.
Price Bundles Below the Individual Total
A bundle should normally offer a clear saving compared with buying every book separately.
Heavy bundles may have higher delivery costs, so compare the total cost with local collection.
Use FREE Listings for Low-Value Books
FREE listings may work well for:
- Small reading bundles
- Baby board books
- Mixed-age books
- Books needing quick local collection
FREE books should still be clean, complete enough for the intended use and accurately described.
Packaging Books
A tight parcel can protect covers from sliding, but too much pressure may bend corners or damage interactive mechanisms. Use suitable packaging, and follow the selected delivery provider’s size and weight restrictions.
Protect books from:
- Rain
- Bent corners
- Crushed covers
- Movement
- Heavy pressure
Use:
- A rigid envelope
- A strong box
- Protective wrapping
- Corner protection where needed
Check Parcel Weight
Books become heavy quickly.
Before setting delivery costs:
- Pack the full bundle
- Measure the parcel
- Weigh it accurately
- Check current carrier limits
Use Tracked Delivery
Use tracked delivery where possible and keep proof of postage until the buyer confirms the order is satisfactory.
Local Collection
For collection:
- Keep arrangements in Kidora messages
- Have the full bundle ready
- Allow the buyer to check the titles and condition
- Mark the order as collected after handover
