I am wondering how can someone publish a manuscript without having any money to pay for the publication costs. I am aware that there are some journals that do not require a publishing fee, however by limiting the choice to only these journals it leaves very few options given the specificity of most journals.
Can the cost be shared among co-authors? Is it common for the first author to ask money to the co-authors to pay for the publishing costs? A previous answer to this did not explain if this is a common practice. Are there certain journals that might waive the publication fee given the financial circumstances? There was a previous question regarding unaffiliated researchers, but what if someone is affiliated but is publishing research from done at the previous institution which does not have money to cover the publication cost.
My field is biology and I am from a developed country, so the option of applying for a publication fee waiver for developing countries is out of the question.
