What is the difference between online journals, e-magazines and e-books?
E-journal/ online-journal is published on the web which can be an online version of the printed journal. E-journals can be subscription based or allow pay-per view access. Whereas e-magazines are like web-sites that contain articles, pictures etc. E-books are nothing but the online copy of a printed book and it is same like e-journal. We can get many e-books which are free to download so we can save the soft-copy of it. Else we need to pay online to download the copy of the book.
The Frontiers online journals publish at irregular frequency, i.e. every time a new article is accepted: we update daily the online list of scholarly articles, linked to the full article content and images, accessible for free to any reader worldwide. Frontiers also publishes a number of e-documents, which can be purchased and downloaded on the website. The e-magazine is an online version of the original hardcopy, crafted in its usual attractive layout, whereas the e-book is a collection of Frontiers articles (Focused Reviews, Themes or Research Topics).
