摘要：The present paper includes details related to the evolution (in 1993 – 2012 period) of some qualitative and quantitative features of the volumes of the journal entitled “Scientific Annals of the Danube Delta Institute”. In the respective twenty years, there were published 798 original articles, but the number of articles / volume decreased along the analysed period (R2 =0.7405) (the most obvious decrease was in case of the articles with subjects related to natural resources and socio-economic aspects). A positive characteristic of the journal evolution was the decrease in percentages/volume of works with few references (the articles without any references being totally eliminated since 2004, inclusively). Other positive aspects of the journal development (in the same two decades) can be considered the increases in some elements of the journal, as follows: percentage of articles that contain lists of references (R2 =0.7322), details related to the authors (R2 =0.5179), abstracts (R2 =0.5578) and key words (R2 =0.7971), number of articles with high number of references (R2 =0.3446 in case of articles with 26 – 30 references, respectively R2 =0.267 in case of articles with more than 30 references) and their percentage / volume (R2 =0.474 in case of articles with 26 – 30 references, respectively R2 =0.4849 in case of articles with more than 30 references).
