Biblio is another second-hand book marketplace. It is targeted at book collectors and is an excellent place to go to for rare and collectible books.
i. Book Conditions
Biblio’s condition classification is a little different to the other sites. They use “As New (AN)”, “Fine (F)”, “Good (G)”, “Fair” and “Poor”
Biblio has a detailed explanation of their Book Condition Classifications here:

Don’t forget that it is the individual book sellers that are assigning these classifications.
In the case of more expensive, rare books, it would be worth ‘asking the seller a question’ to get more details, before committing to a purchase.
ii. Book Seller Ratings
The ratings on Biblio are based on ‘order fulfilment rates’ for the previous 90 days, rather than customer reviews. “Order fulfillment is the percentage of orders placed with that seller which were filled.”
This is unlike the other sites, where user ratings are incorporated into the star system.
iii. Delivery
The delivery costs are clearly displayed underneath the book price on the search results pages of Biblio:
