The core belief at Interline Publishing evolved with the changing requirements of the reading community at large and student community specifically. This belief is centered on the current requirements of needing context specific content real time. A user could upload or read for free or pay to download content specific to their requirement by defining their need giving details such as name of the paper, title of the chapter, semester, institution, university etc.

The users are broadly categorized either as author or reader with possible overlap of roles. An author uploads content giving areas of potential use and a reader seeks specific content by defining search parameters. The help menu in the title bar explains specific functionalities and enables optimal exploitation of the facilities on offer.
