The journal, abbreviated Rev. Anal. Numer. Teoria Aproximației has appeared for only three years, two issues per year, between 1972-1974.
The papers were written in Romanian and this journal had no connection to the other journal edited at ICTP, Rev. Anal. Numer. Theor. Approx., despite their names were related (one was in Romanian, the other its translation in French).
