As someone who has recently gotten into the research world, I read a lot of preprints and occasionally dig up some technical reports to access older publications.

To me, it seems like technical reports were the paper version of preprints. Many technical reports appeared later as peer-reviewed articles or chapters of books. Nowadays, there are far fewer technical reports appearing. My department used to produce multiple dozens each year in the 70s and 80s, but they have only produced one so far this year.

Does this mean that preprints have taken the place of technical reports? Is there any reason why a researcher would choose to publish a technical report with their university or organization?

I’d like to put two preprints on OSF to make them available for everyone. One paper is already published, the other is in print. I’ve checked on SHERPA/RoMEO if the publisher allows preprint to be put on another server and everything seems to be ok. For example for the Journal “Nursing Ethics” it says “author can archive pre-print” and “author can archive post-print”.

I then tried to upload the preprint to OSF, but I don’t understand the option for licensing. I can either choose

- CCO 1.0 Universal
- No License
- CC-By Attribution 4.0 International

I’ve read the FAQs on licensing but I don’t understand these options well enough and I’m wondering if the right choice depends on the publisher’s copyright policy. So which one shall I choose?

I am new to arXiv and when I asked several of my colleagues which license I should select for my submission, they tell me to use the one marked as default, referring to the “arXiv.org perpetual” license. However, the statement that implies that “perpetual” is default has been removed apparently. I am simply asking to find out why that is, and if anything important has changed recently.

Here is what the first page of an arXiv submission looked like in 2012, according to this blog:

Notice the underlined statement: Select arXiv perpetual unless you know exactly what you are doing.

Today it looks like this:

The default qualifier statement is gone! Why is that? Has anything changed?

In my article, I have cited a preprint version (arXiv) of one references. After my article has been published in the final form, I received a request from the author of the preprint article asking me to make Corrigendum that tells the readers about the journal version of his cited article. I am new in the publication field and I want to know whether I should obey to his demand and make the corrigendum or leave the citation as it is.
I might mention that the contents of both preprint and journal versions are similar and the version that I have read and referred to in my manuscript is the preprint as the journal version was not available at the time I wrote the paper.
Thank you for your advise.

I am a student who is very enthusiastic about open access and sharing research. When I worked with my former supervisor, we would write a paper and then post it to a preprint server (e.g., arXiv) at the same time as submitting it to a venue. My current supervisor, however, is of the mindset that we should post a preprint after receiving confirmation that the paper was accepted to some venue.

Is there a generally-accepted time to post a preprint?

I recently wanted to read one conference paper and one journal article. The conference paper is named Division by invariant integers using multiplication. By clicking on the “All 9 versions” link on Google Scholar, I found the full paper on gmplib.org.

The journal article is named improved division by invariant integers. It is also available at several sources as PDF.

Why do publishers allow such redistribution of papers / preprints? I mean, if everyone is doing the same as I’m doing, the main revenue source of publishers will go away. Is it because publishers obtain their main revenue from university libraries? If I can’t find a PDF preprint of an article, the next thing I’m going to do is to try to find the article through my university library.
