The diaries are presented in the form of separate notebooks which were written by Milan Jelínek over a continuous, yet not daily, period of time. Jelínek recorded his everyday impressions, commenting on current events; a large part of them are summaries and short reviews of the books he read. The diaries prove the mindset of an enthusiastic Communist transformed to a critic, and the disappointment of the social and political development following the Prague Spring. There a also very valuable and non-encrypted, "uncensored" records about the publishing of samizdat titles and the organisation of the underground university within the activities of the Jan Hus Educational Foundation. What is interesting, are also the characteristics of other people from the academic and dissident environment.
