There is no specific number! However, an average of 1-2 a year would be good enough.

It's a question that may seem simple at first. Between duty and obligation. Once a professor at a German University told me: "when you are forty years old you should have at least 2 or 3 published books and about 15 published articles, several of them in English".

perhaps because it is a question that goes round and round in the heads of many...

at least it happens to me and it's not nice to deal with this kind of situation. I want to write and publish at my own pace, I don't like anyone imposing anything on me.

Для России количество публикаций в год все больше становится показателем результативности деятельности преподавателя университета. В разных университетах это количество колеблется от 1 статьи в год до 5 статей в год. При этом достаточно часто тематика статей должна быть связана либо с научной темой, которую разрабатывает университет, либо с преподаваемыми дисциплинами.

The problem that arises there, dear Andrej, it seems to me, is that the faster the publication, the lower the quality not only of the publication, but also of the Journal. Many of these have a rather lax and fast evaluation system. An indexed Journal sometimes takes a year to publish an article.

I don't know if this system is understood by many university bureaucrats who want instant results; and then make a graph and show it to the dean.

Уважаемый Пабло!

Когда встает вопрос о количественном плане, вопрос о качестве отходит на второй план. Главным становится показать, что все занимаются научной работой. Из этого вытекает и другая проблема. Тот, кто мало пишет, для того чтобы выполнить план, стремится присоединиться в качестве соавтора к пишущему человеку.

I completely agree.

It actually happened to me that I had to write an article alone, but in the end the head of the department "suggested" me to include her as a co-author. And this fraud in seemingly small doses is magnified in other matters. In the end, the researcher becomes a puppet of department heads or other managers?

There is no specific number! However, an average of 1-2 a year would be good enough.

it depends what type of research you are doing... sometime one article in lifetime could be enough

One per a year is fair enough

yes, if you can convince your boss... some of them could argue about that

I agree with Hassan Izzeddin Sarsak

1-2 publications per year is attainable by most of us.

I think three research a year is great and useful

I think the same, but for a index journal I should start working now to be published in 2020?

And what is more important - a quality or a quantity?

The demand for quantity can lead to "dilution" of the nature of the problems into multiple articles. Is this the goal?

And book every 1 or2 yers - terrible vision! It is no time for research - we must only write and write and write ... :-)

of course! but go to tell the people who want numbers and statistics

How many articles/books should a researcher publish or produce per year?

First, it depends on a field/domain of the science. Second, It also depends on the type of a publication - a research article, a review paper, a monograph, a textbook, etc.. Third, it depends on a publication target - a journal, conference material publications, a project summary/results/report, a magazine/newspaper article, a chapter in a book/the entire book, etc.. Forth, it also depends as to whether researchers are totally dedicated to research, or they also share this activity with a teaching load - those are entirely different stories.

In theoretical disciplines, the less authors, the sooner an article can be completed. Whereas in predominantly experimental articles, the more co-authors, the sooner the article can be completed. For instance, in physics, experimental articles may require from three to seven month to complete. Experimental research in a tight cooperation with theoretical physicists may either short it down, or extend typical times to complete an article, depends on the nature of the results obtained. Usually, 2-3 original journal articles in two years is a quite good research efficiency. A monograph/book based on own original and reviewed results may take from seven month to a couple of years to complete.

Does it vary too much between disciplines?

Absolutely. It varies. It's hard to say whether it's 'too much' or not, but it does vary. I would say, if one compares computer simulation/modeling only based sciences to an experimental science like physics, the time to an article completion could be reduced up to approximately ~50%, whereas if one compares field sciences like geology, archaeology, and alike to physics, the time to an article completion can be extended to approximately ~ 100% - 150%. All those percentages are just my rough assessments - there's nothing scientific in that, just a matter of a personal experience.

indeed, thank you for your contribution

What do you think Tamara?

It depends upon the type of publication and specialities as well as research facilities. It is well said and described by Dr Len Leonid Mizrah.

Asking for research articles in peer reviewed journals and presentations in conferences/ seminars are becoming common now a days. As you pointed out, one may ask for books also in coming years. Writing quality articles are tough and this depends on current research, projects, collaborative works etc. For a researcher there should be no restriction in articles but one can publish one or two peer reviewed research articles a year.

I think there shouldnt be a limit. As tesearchers we should focus on quality, because the published work would be around for long even after we are gone.

of course Reuben
