Sources and istoriografiyaProblema constructing source base for exploring the history of the University of Moscow in the period under consideration - from the beginning of the XIX century. Moscow before the fire - is particularly acute, which is primarily due to the complete destruction by fire the entire corpus of documents stored in the archives of the university offices, as well as the university library and museum collections. Thus were lost material relating to the activities of the Board and the Board of the University, correspondence council with the trustees of educational districts, track records of professors and teachers, the documents of accounting and control progress and attendance of students and high school students, copies of certificates and diplomas issued to students after graduation (originals these documents can be found in several private collections). Together with the burnt library disappeared and rare editions of the university, there were only a few instances (for example, the Company began to produce stories and Russian editions Chronicle Antiques). Lost collection of university museums contain artifacts, which had a huge, not only scientific but also historical value. Along with them were burned, and many private collections of university professors, along with their diaries and letters, telling about the life of the university in Moscow dopozharnoy. Almost completely lost training equipment university laboratories, physical, chemical, and medical office, the lack of descriptions which deprives us of essential information about the development of the university science at that time.
