I have published in journal X and given them the rights to my work. In the "Author's Rights" clause, it says that I am allowed to post my work to pre-print servers (in the form immediately prior to publishing and sticking the copyright on) such as arXiv.
I am also allowed to distribute the copyrighted version for teaching and technical purposes, conference presentations, or other scholarly activities, and also allowed to post the copyrighted version to a personal website.
Here are my questions:
I can't understand the logic behind why I am given so many rights. Where does the journal make money? In what scenario does someone want to read my work and not very easily find a free way to do so?
I realize that if someone wants to cite my work, they have to cite the official version, which boosts the reputation of the journal. Is the main point that journal subscriptions negotiated with research universities have more bargaining power, based on impact factor?
I am planning on posting my work to a pre-print server while referencing the official DOI of the copyrighted version. It simply feels odd to me, even though I know it's perfectly legal.
What am I missing? I realize all journals are different, but I want to better understand why author's are given these rights. I feel like a copyright transfer is a big deal.
From my perspective, I want eyes on my paper. From the journal's perspective, they want money from my work. How are there so many subscriptions to journal X if it's so easy to get ahold of the papers for free?
