Until now, several authors wrote about Jovan Tomić, highlighting some parts of his life and work. The necessity of the apparition of more detailed monography about this personality was the author's intention to point out the unused documents that can serve for a better and complete recognition of this personality. These so-called "new documents" are located in Archive of Serbia and are associated with several area of Tomić's work. First, they are giving a detailed description of the most difficult period in his science work - his failure at the election for the professor of the High School, and all about what was happening at the time. There are also data about his work as Director of National Library, on a very particular field, and his activity in the ex - State Archive, today Archive of Serbia, as a member of the Board of this Institution. At the end, the bibliographical errors, from the book "Archive material about the National Library of Serbia", tome II, conserning the date of birth and dead of Jovan Tomić, were pointed out. In one word, in this summary, four data's, not yet published before, are given here, and they made a contribution to the bibliography of Jovan Tomić.
