Could an online booksharing scheme spell the end for the traditional library?
A scheme where residents post their own books online to swap, then meet to complete the transaction has worried some library campaigners

With more people using the internet, an online booksharing scheme might appear to be the perfect solution for people unable to visit their local library. But the idea has caused dismay among some library campaigners. The London borough of Sutton last Monday launched its online booksharing scheme where residents post their own books to swap, then meet in person to complete the transaction.
Registered users upload details of books they want to share using open source data. Once they tap in the ISBN, a small picture of the publication appears with a few explanatory notes and the owner’s details. Borrowers can then get in touch to agree loan terms and where to meet.
