The 400 year history of the Vilnius university has found reflection in many publications. The first attempts to bibliography the University history were made in the XVII century publications which, besides the material on the University activities, gave the information about the University professors and their scientific works. With the rise of bibliographic activity there appeared some prominent publications, recording the material about Vilnius University. Those were the works by A. Jocher, J. Bielinski, L. Finkel, L. Janowski and some others. The most important Lithuanian works about the old Vilnius university were published by S. Baltramaitis and V. Biržiška. The history of the Vilnius university, reopened in 1919, is shown in the publications of Stephen Bathory university and the bibliographical index compiled by M. Ambros, presenting the material about the University, given in the chronologically-subject order. The Lithuanian University which existed at the same time in Kaunas, published its own bibliographical indices; the University professors' publication index was published by P. Dilys in Chicago. Material about the University activities was also published in the journal „Bibliographical news" („Bibliografijos žinios").The Soviet Lithuanian bibliographers have collected much material about the history of education and science in Lithuania, which is published in independent publications. The most important of this kind are: „The Soviet Lithuanian Higher Schools", „Vilnius University. Bibliography. 1940–1977", which register the material giving the present-day evaluation of the University's 400 year history. Special bibliographies as well as bibliographical data, collected in monographies and articles on the history of science by Lithuanian scientists, can also be regarded as bibliographical sources about the Vilnius University.
The history of Soviet Lithuania's libraries during the Great Patriotic War is a part of the Soviet Union's library history. It investigates the library service to the evacuees from Lithuania, the dissemination of the Communist press in the territory occupied by the Hitler army, the damages inflicted to the libraries by the invaders and the restoration of the libraries after the liberation of the country. Studying this period one meets difficulties as the archival documents are very sparse and the memoiristic materials are still not collected and analyzed.
Posibilities of securing scientific research with information are being viewed in the article as w ell as juridical status of information worth. Creative work of the author and information process are mentioned in accordance with union republic legislature (with standarts of copyright).
The investigation of information needs in the Institute of Chemistry and Chemical Technology of Academy of Sciences Lit. SSR allowed to draw conclusions about sources of information necessary for researchers, forms of information supply for electrochemists and time needed for reading of scientific literature. Profile interests turned out too, they were brought together into "Rubricator of profile interests of the Institute". (List of headings).During the first stage we found out, that use of sources of information (except manuals, industrial catalogues, standards and translations) straightly depends on scientific qualification of specialist, on his duties.The higher are those indexes the more sources of information are used by specialists. The use of sources of information is influenced by the kind of the field in which scientist works.The use of sources of information dealing with literature (except the express information services, bibliographical catalog and encyclopedias) depends thoroughly on the scientific qualification of specialists, on their duties. The kind of the field in which the scientist works influences use of those sources.Forms of informational supply depend on scientific qualification of specialist: Doctors value analytical and abstract surveys (45,5). Scientists of this kind are interested in the guidance of librarians. Doctors need less help from scientific and technical information services and librarians in order to obtain factographical data.Great part of young scientists recognizes that serious part of informational supply is „guidance by librarians in the selection of information dealing with a special theme." 23,1 % specialists without scientific degree recognize this kind of assistance to be necessary. Analyses of results of questionnaires enables to draw a conclusion, that time, which is needed for selection and editing the collected literature depends on the duties and qualification. It was defined that researchers with high qualification spend more time for looking over and reading scientific literature in comparison with specialists without scientific degree.During the second stage of the investigation turned out profile interests of Institute scientists. Profile interests were brought together into „Rubricator". Its analysis enabled to define inner and outer relations between electrochemistry, galvanotechnics and other branches of science.According to the analysis of card file interests, the greatest part of electrochemists (72,3%) value part of "electrochemistry", second place occupies "electrochemical methods of protection", on the third – "technologies of organical material" (37,4).
