A journal published and distributed in electronic form, mostly online on the Internet.
E-journals are both online-only or electronic versions of printed journals.
Most scholarly and academic journals are at present produced and made available as e-journals, because of the relevant advantages in terms of diffusion, accessibility, impact.
Costs are largely influenced by publishers' policies; the open access movement has an important and increasing role in the e-journals market.
* if you mean just ONE publisher you should say "the publisher's policies". But I think you probably mean publishers here, so you should say "publishers' policies" (or "the publishers' policies" both correct but with a slightly different angle)
