Let us discuss the journals published on the basis of "Pay and get your article published". How reliable are they? I await your views and comments on the subject matter. Thank you all in advance.
In my view, i do not consider them very trustworthy. In most cases I encountered, they will take away your authorial rights, which is what a decent publisher should not do. I would not believe any e-mails inviting you to publish somewhere either.
Crystal Maraj: Publishers are privat enterprises, so they have to pay their staff, pay for their offices, for all hardware, for software, for advertisement, pay taxes, etc. Large publishers with high-ranking journals are mostly stock companies or similar and therefore they also have to pay dividends to stockholders. However, as for all companies it is nearly impossible to get details of their business model.
