The development of information technologies for creating, storing, processing, transmission and use of data in the form of messages and information flows, as well as the rapid growth of digital information and information resources made it necessary to clarify the classical approaches to identify aspects of information and ways to measure their volumes. The traditional approach is based on the measurement of the volume of syntactic, semantic and pragmatic components not quite fully reflects all the qualitative aspects of information communications and information flows due to the presence of their dominant share of the emotional component. It is proposed to allocate the emotional aspect of additional informational messages and flows, to measure its volume based on the proposed methodology. The paper analyzes the necessity of refining quality characteristics of information messages and information flows. The work objective is to identify high-quality aspects of information messages and flows under conditions of sharp increasing the amounts of stored and transmitted data in a digital format, and developing the mechanism of the volume assessment of an emotional component of an information message or information flow. Studied problems are the following: to analyze dynamics of the growing amount of digital information in world information resources; to consider the classical approach to measure information based on syntactic, semantic and pragmatic aspects; to show the value and share of an emotional component in information messages and information flows; to offer evaluation methods of an information emotional component volume. Data for a research are obtained from the Internet open sources, educational-scientific literature. The data analysis has been carried on by determining structural logical relationships of the researched object. Main logic: 1) growing amounts of digital information is observed in the world; 2) dynamics of the pragmatic (most valuable) component share is considerably lagged behind at the background of such rapid growth; 3) it is necessary to resolve a problem: «What is the main part of digital information amount consisted of?»; 4) as there are consumers of information resources with extremely low pragmatic usefulness, developers of such resources pledge in them an additional emotional component to involve the greater audience; 5) quantitative indices of information sources activities should be used to assess the information emotional component amounts. The obtained results are the following: a relative share of the pragmatic component promptly decreases at the background of rapid growth of digital information amount; the emotional component of information messages and flows is the most significant while measuring their amount and quality; it is offered to estimate the degree of the information resource emotional efficiency by means of an aggregative dimensionless indicator; saturation of information messages and flows with an emotional component should determine further tendencies of upgrading the information space, including library resources.
