Unesco presents a library statistics program, including definitions and classifications. It recommends close cooperation between national and international bodies with a view toward improving access to, and the comparability of, library statistics. The section on book production statistics explains the standards set forth in the recommendations, i.e. the definitions, and the system of classification and tabulation, and draws attention to the practical difficulties which may arise in their preparation. The section on mass media suggests: a means for recording relevant and useful data in the field, techniques for the collection of the data, and from whom it should be collected; ways of handling, storing and analyzing the large quantities of data collected; and standard tabulations of the data to provide a general picture of mass media in each country. Examples of the questionnaires used are included and mass media definitions appended. (For the final report of this seminar see LI 002 907) (MM)
