The article analyzes the state and development of technologies of effectiveness of science researches evaluation in conditions of rapid development of science and progressive accumulation of huge scattered arrays of scientific information. Bibliometric indicators of science researches effectiveness evaluating such as the Hirsch index of scientist, journal impact factor and alternative metrics are analyzed. Technologies of its calculations, advantages or disadvantages in use are highlighted. Fundamental principles of Alternative metrics manifesto that appeared due to rise of a wave of attempts to opposite or to make an alternative to bibliometric indicators are considered. It was noted that technology uses altmetrics unlike traditional bibliometric, more fully takes into consideration the activity of social networks, blogs and other services, that are designed for Internet users of science products and its impact on science and society. The paper highlights 10 principles of Leiden manifesto for scientometrics where modern developments in the methodology of evaluation of scientific activity are outlined. It is indicated that its compliance will help to reveal breakthrough research fronts and shall remove the priority from purely quantitative measurement of research activity, providing a wide range of scientometric and bibliometric indicators for independent and transparent expert opinion of the effectiveness of research activity. The study comes to conclusion about expediency of mutual using and expanding of functionality of bibliometric tools for a more complete disclosure of spreading of science.
