Purpose - The aim of the paper was to quantify the basic parameters of the publication activity of the Czech Republic, to compare them with the publication activities of other countries, to quantify the share of countries with a larger or smaller annual increase in documents to the Scopus database and to look for connections between the annual increase in documents and the H-index of the countries and other parameters. Design/Methodology/Approach - The data was obtained using selected indicators on the SCImago Journal & Country Rank portal, and further processed using the Excel statistical tool. Results - The creation of the Scopus database is mainly carried out by countries with a high increase in documents. In 2020, China came first in the annual increase of documents, surpassing the US for the first time since 1996. Documents by authors with affiliation to the Czech Republic account for 2.54% in all fields and 4.29% in the field of Agricultural and Biological Sciences within the EU-28 countries. Among V4 countries, the Czech Republic has the highest annual accretion of documents per year and also the largest share of document creation per capita. Originality/Value - The work is original in the way of processing the data obtained on the portal. The other benefit is the evaluation of the publication (scientific) activity of the Czech Republic and its comparison with other countries. [ABSTRACT FROM AUTHOR]

The study deals with the identification systems based on EU standards URN:NBN. For the analysis were selected systems in Finland, Italy, the Netherlands and Germany (The German system provides services for Austria and Switzerland too). The paper analyzes the technical solutions and national diversity of individual cases implementations of the URN: NBN standard. The study in the introduction gives an overview of the identification system for digital documents and describes in detail the standard URN:NBN. The main part of the study is based on a comparison of selected categories (object of identification, participants in the system, the syntax model and the rules of system) of various national identification system, including systems ČIDLO (Czech system based on standard URN:NBN). The study aims to present the possibilities and limitations of the system using standard URN:NBN and to emphasize its role in the processes of long-term preservation and accessibility of digital documents of national cultural heritage.
