During its first launching year 2016, that is for Vol. 1, Nos. 0/1/2, all articles on the TPJ will be on Open Access: no publication fee for the Author, no fee for anyone to read any article. 
Starting in 2017, that is with Vol. 2, the Author will have two options: either pay a publication fee [amount and schedule to be posted in due course] and have the article be on Open Access, or pay no publication fee and have the article be accessible only for subscribers or readers willing to pay a reading fee. A detailed policy will be posted soon.
