Book spines get plastered with all sorts of colourful imagery and text -which then usually looks grotesque lined up on a bookshelf.
Today’s invention offers an alternative. A small printer, like a labelmaker, has a barcode reader to identify each book.
It is then used to print the Title and Author of each book onto the page edges (just as we used to scrawl our names in biro, at school -except this would be in a tasteful, uniform font).
This allows books to be placed with their spines facing inwards and the page edges forming a useful, attractive, array.
