The journal Bulletin of Number Theory and Related Topics (Boletín de teoría de números y temas conexos) does not seem to have its own website, from where one can obtain article/paper submission details and instructions. (I am interested in submitting a paper to this journal for possible publication.)
I did find the following search facility for the journal in the Hathi Trust Digital Library. But then again, no mention is made as to the submission details/instructions that I require.
In Chapter 1 of the book New Visual Perspectives on Fibonacci Numbers (Introductory Remarks [by K T Atanassov]), the author mentions (in page 4) that "[he] sent some [of his results] to Professor Aldo Peretti, who published them in Bulletin of Number Theory and Related Topics". (It appears that Professor Peretti is the Editor (?) of the said journal.) However, when I try to Google for Professor Peretti's e-mail address, no helpful results are returned. Additionally, I tried to search for Peretti's papers in the arXiv (if any), and found none, and therefore was unable to get hold of his e-mail address.
I am posting this question here in the hopes that someone with better Internet search skills can enlighten me.
