I live in Korso, Vantaa. Does anyone want good used (mostly) novels in English? Soft- and hardback.

The Lumo library in Korso has a book recycling point in the Lumo building's lobby.
The instructions are as follows:
"Recycling point for books brought in by customers. Bring up to five books at a time. You can take as many as you like."

There is also a book recycling point in the lobby of the Korso shopping centre (the one with the S-Market, a flower shop and others).

In addition to these, the capital area recycling centres often take books.
