Human evolution is a continuous process that evaluates and contributes to the emergence of modern people, people with current knowledge of the 21st century. Personal development is the growth of the person regardless of the final goal - career, education, social life, personal life etc. Personal development appears with a well defined term "Andragogy", which is formed from the Greek words ἀνδρ- (andros), meaning "man/human", and ἀγωγός (gogos), which means lead. Therefore, the science of Andragogy means "leader of man" Andragogy is the science of adult education and it applies certain methods and principles used in their education. The term "Andragogy" is also explained as - "a set of guidelines", "a theory of adult education and training', 'the art and science of helping adults learn', 'education continuing', 'continuing education', 'mature education', etc. Androgogy is also the power to learn and improve continuously, especially for people deprived of their freedom. Limitation by law of some rights does not automatically cancel all other rights of some people. If we are talking about people held in prisons, even if they can no longer move freely nor manage the time they have at will, they continue to have the right of access to education, just like any citizen of our state. A prisoner may and has the right to learn from practically anything during detention. Deprivation of liberty produces suffering and a degradation of personality, and education can play an important role in limiting these consequences. The negative effects of detention – depersonalization, institutionalization, desocialization – are those that justify, for the benefit of education in penitentiaries and which requires greater resources and efforts. The involvement of libraries will contribute to non-formal education for adults that can contribute to the normalization of the abnormal situation that is detention.
