IJPS provides immediate free access to its content on the principle that making research freely available to the public supports a greater global exchange of knowledge, meaning:

• Everyone has free and unlimited access to the full-text of articles published in IJPS; manuscripts are freely available without subscription or price barriers.
• Open Access publication is supported by authors' institutes or research funding agency by payment of a comparatively low Article Processing Fee (APF) for accepted articles.
• Open Access publication is more frequently cited due to their high publicity and availability.
• Articles can be shared and adapted, provided the attribution for the work is given and that the work is not used for commercial purposes.

The open access policy of the IJPS aims at increasing the visibility and accessibility of the published content. Online free access and listing and indexing in a larger number of bibliographic databases add to the high visibility and research impact.
