Open Access publishing is costly and we charge authors for this. Starting with Fall 2019 IJP levies an article-processing charge of 6.000.000 Rls or 250$ CAD, for each original, short communication and case report article (not Reviews, Minireviews or Letters-to-the Editor) accepted for publication. Please note that these charges apply to accepted articles. Invoices are issued only for accepted articles by the editors. The article processing charge must be paid before the manuscript will be published.
