• Ancient Greeks had inscribed above the entrance to a library in Thebes, the words 'healing place for the soul.'
• At the end of the nineteenth century, Sigmund Freud began using literature during psychoanalysis sessions.
• After WWI, a course of reading has often been prescribed to traumatised soldiers.

It is a book written in the style of a medical dictionary that matches ailments with suggested reading cures. But the book has a twist: each local editor can adapt up to twenty-five per cent of the ailments and reading recommendations to fit each particular country's readership.

A study showed that, when people read about an experience, they display stimulation within the same neurological regions as when they go through the experience themselves.

Reading allows an escape from ordinary, everyday pressures. It makes us lose all sense of self, while also putting us in perpetual union with another mind.

One major woe of modern readers is that they are overwhelmed by the number of books in the world.

But although more books are published than ever before, people are selecting from a smaller and smaller pool. Considering how many books you're likely to read before you die, you realise that you need to be highly selective to make the most of your reading time. The best way to do that is to see a bibliotherapist.
