Since the Mediterranean Journal of Hematology and Infectious Diseases, as all the online publications of Mattioli 1885, does not apply subscription charges for its research content, it can defray publishing costs from the Article Processing Charges. Until now these costs have been faced by different organizations; unfortunately, this support is no longer achievable. We are therefore compelled to sustain the Journal by applying a fee of 600,00 € for each article (except invited Reviews, which remain free of charge).Starting from 1-1-2019, all articles, excluding Reviews by invited authors, will be processed after receiving a subscribed declaration by the authors they undertake to pay a fee of 600,00 € (+ VAT, if any) in case of acceptance for publication. The Article Processing Charges will have to be paid to the Publisher; instructions are given in the Journal’s Guidelines (https://mattiolihealth.com/shop/publication-fee-mediterranean-journal-of-hematology-and-infectious-diseases/ The Editorial Board of the Mediterranean Journal of Hematology and Infectious Diseases is engaged in improving the quality of the papers published in our journal. So, with the agreement of the Publisher, the possibility of publishing in MJHID without charge will be extended to the authors of the five papers which obtained the most citations which contributed to Impact Factor of the year throughout the two years following.
