The result indicates that the scientific papers of the world have had an increasing trend in this field. H-index of articles was 93 and 18 in the world and Middle East countries, respectively. The United States of America (USA) had the highest number of articles (2221) with h-index 81. Iran had h-index 7. It was found that single-authored paper had the highest frequency among global papers. Scientific collaborative coefficient was 0.44 and 0.54 for global and Iranian researchers during 35 years, respectively.
The research results suggest that most scientific articles of digital libraries have been published by several countries, with the USA topping the list. In the Middle East, Iran has the largest share in science production with 41 articles.
