Patients in Hertfordshire with certain mental health problems are to be prescribed books.
Those with mild to moderate mental health problems will get the books as a first step in providing information and ways to manage their condition.
The books on prescription scheme is used throughout the UK for patients with mental health problems, and the book lists are designed to help them.
The scheme was first piloted in Cardiff in 2004.
Keith Emsall, Hertfordshire County executive member for culture and community safety, said: "It is a confidential scheme which supplements normal medical treatment rather than replaces it and people are advised to return to their doctor if they don't find it helpful."
More than 40 specialist books are available covering conditions ranging from anger or anxiety management to dealing with bereavement, eating disorders, postnatal depression and weight problems.
The scheme is available in all libraries, including mobile libraries.
