Open Access

Our goal is to make all the research and publications of PTC available to the general public on Open Access.

Open Access is a broad international movement that seeks to grant free and open online access to academic information, such as publications and data. A publication is defined ‘open access’ when there are no financial, legal or technical barriers to accessing it – that is to say when anyone can read, download, copy, distribute, print, search for and search within the information, or use it in education or in any other way within the legal agreements. 

Open access is a publishing model for scholarly communication that makes research information available to readers at no cost, as opposed to the traditional subscription model in which readers have access to scholarly information by paying a subscription (usually via libraries). 

The publications of PTC are available for free.
