I’ve personally used Shelfari for the last few years. It’s an online social service for books in which users create bookshelves and share that with others. One great aspect of it is the bookshelf widget that you can create and place on websites. I thought this would be a great addition to our parish website to provide book suggestions to others. We haven’t set this part up, but purchasing books is linked to Amazon and you can create an Associate Id with them that would provide additional revenue in the form of a portion of each sale back to the parish.
You can see an example by visiting our ‘Reading Room‘ page on our website.
