What is the difference between online journals and ebooks?

Frontiers journals are published exclusively online with new articles published on a rolling basis. Articles appear on the journal’s main page as shown below with links to the full article content and images. They are accessible at no cost, anytime, and to any reader worldwide.



Frontiers also publishes ebooks arising from Frontiers Research Topics which are collections of published articles on a specific theme. These can be downloaded for free as PDF or EPUB files from a research topic page as highlighted in the below example.


Note that not all Research Topics have ebooks. You can search ebooks on our Research Topic page as suggested in the below image.



Alternatively, Research Topic Books (ebooks) can also be searched on our book portal (see below image).
