Explain what people are bringing
Invite each person to bring a small number of books they genuinely want to give away. Make clear that the exchange is permanent rather than a loan, unless you plan to organise lending separately. A book with sentimental value should not end up on the table through misunderstanding. Copies should be complete and in readable condition.
Welcome guests who have no books to contribute. A flexible arrangement in which people choose one or two titles, depending on availability, may work better than a system of equivalent values. A recent hardback does not need to earn more points than an older paperback someone enjoyed. The purpose is circulation rather than pricing collections.
Introduce without retelling the plot
Arrange books with titles visible. Each person can briefly explain one reason for bringing a title: a narrative voice, an idea or a memorable passage without revealing the ending. Avoid promising that everyone will love it. A personal preference is an invitation rather than a universal verdict.
Allow time to read cover descriptions and sample pages quietly. If two people want the same copy, agree a simple solution such as drawing lots, making another choice or arranging a later loan between them with mutual consent. There is no need to turn the decision into a contest over who cares most about literature.
Plan for the remaining books
Decide beforehand whether unchosen books go home with their owners or are donated somewhere that accepts them. Check donation requirements: libraries and organisations do not necessarily accept every kind of book. Do not leave a pile outside a closed building.
Slip a removable card into each book with a question or impression if you like, rather than writing on its pages. If the exchange prompts another gathering, keep it optional instead of creating a reading deadline. Someone can appreciate receiving a book without having to finish it by a set date or report back to the person who gave it.
