The prisons of Bolivia encourage inmates to read books by reducing their jail time.

Having been applied in Brazil, they aim to spread literacy and give hope despite a notoriously slow judicial process.

The state program "Books Behind Bars" offers detainees a chance to get out of jail days or weeks in advance of their release date. Bolivia does not have a life sentence or death penalty, but pretrial detention can last for many years due to a slow judicial system.

The program has been launched in 47 prisons that do not have resources to pay for education, reintegration, or social assistance programs for prisoners, the Andean country's Ombudsman's Office says.

So far, 865 inmates are sifting through prose, improving their reading and writing skills. One of them is Jaqueline, who has already read eight books in a year and has passed four reading tests.

"It is really hard for people like us who have no income and who do not have family outside," she said. "There are people here, for example, who are just learning how to read and write."

Nadia Cruz with the Ombudsman's office said the intention is to encourage inmates awaiting trial.

"That is important because what is reduced (on the sentences) is relatively little, it is hours or days in some cases, depending on what the board decides," she told Reuters.

With a daily salary of 8 bolivianos ($1.18), incarcerated Bolivians are forced to work to be able to eat and pay the high court costs to be released.

The country's prisons and jails have long suffered from overcrowded and unsanitary conditions, with some detainees staging protests over the lack of health care, according to Human Rights Watch.

Amid these difficulties, learning to read can be like escaping the prison walls, at least in the mind, said Mildred, an inmate at the Obrajes women's prison in the highland city of La Paz.

"When I read, I am in contact with the whole universe. The walls and bars disappear," she said.
