We always hear about the increasing number of publications published every year and the resulting information overload in science. I wanted to show this trend to students to highlight why they should care about information literacy and search strategies. Unfortunately, I couldn't find a reliable source that highlights this trend, e.g. in an easy understandable figure.



I searched for publications including this information and even hoped for Web of Science or Google Scholar to publish this information but couldn't find anything useful. It is not that important what kinds of publication types are included, e.g. only journal articles or all kinds of publications.



Has anyone a reliable and relatively easy to understand source highlighting the trend of increasing global number of publications over time?

  • Microsoft's Academic search team presented such a chart at the 2016 Microsoft Academic Summit in New York. My recollection is that the overall trend was about 7 percent per year growth in citations, going back to the nineteenth century. The trend was steady, with three exceptions: Major drops during the World Wars, and lack of growth during the Great Depression. If anything, the growth rate was higher in recent decades. I helped prepare the results, but I do not have a copy.

I found an archived version of the 2018 MTS Report. Among other statistics, it has this plot of the scientific output from 1975-2018 and four different databases:



2018 MTS Report



The Web of Science (WoS) line looks rather similar to the earlier results of Bornmann and Mutz (2014), who produced this figure for 1980-2012 using a copy of WoS' database:



Exponential growth

  • Thank you, this is a good starting point. Yes, it would be great to have more up-to-date numbers. According to this blogpost we already hit the 2.5 million publications per year in 2015 but the cited STM report from 2015 is no longer available online. Could be up to 3 million per year now ...

For the field of mathematics, another source of data is the AMS Math Reviews (MathSciNet), where this type of information is readily available (just search for the year you want). Virtually every reputable math publication gets indexed there nowadays. Also, unlike something like Google Scholar, only reputable journals get indexed and each publication appears only once. Math Reviews is a paid service, so you'd need to be affiliated with a university with a subscription. (I don't know how complete this data is as you go further back in time. Maybe someone else has a better sense of this.)



For example, here are the total number of mathematics publications for various years at 10-year intervals.



2018: 111,018;
2008: 99,268;
1998: 67,807;
1988: 55,420;
1978: 36,637;
1968: 19,615;
1958: 10,249;
1948: 5,456;
1938: 1,417;
1928: 1,439;
1918: 632;
1908: 729;
1898: 710;

    arxiv.org presents his own statistics, but be aware that a lot of publications from humanities and biomedical sciences are missing in this statistics:



    enter image description here



    This chart also shows the exponential trend on arxiv.



    Long-term chart:



    enter image description here



    Very long-term chart:



    enter image description here



    There is also biorxiv covering the missing biomedical scientific branches, much younger than arxiv but there is a quite detailed statistical report on its growth.



    Publication: Attention decay in science (due to exponential growth)



    (To me it's also interesting how this correlates with the number of PhD students in another answer and how this can be explained... did internet boost scientific productivity and/or number of PhD students?!)

      Note that arXiv has progressively expanded its scope, so the growth in the linked chart will partly reflect that, as well as changing attitudes to preprints in some subfields.

    For the field of mathematics, another source of data is the AMS Math Reviews (MathSciNet), where this type of information is readily available (just search for the year you want). Virtually every reputable math publication gets indexed there nowadays. Also, unlike something like Google Scholar, only reputable journals get indexed and each publication appears only once. Math Reviews is a paid service, so you'd need to be affiliated with a university with a subscription. (I don't know how complete this data is as you go further back in time. Maybe someone else has a better sense of this.)



    For example, here are the total number of mathematics publications for various years at 10-year intervals.



    2018: 111,018;
    2008: 99,268;
    1998: 67,807;
    1988: 55,420;
    1978: 36,637;
    1968: 19,615;
    1958: 10,249;
    1948: 5,456;
    1938: 1,417;
    1928: 1,439;
    1918: 632;
    1908: 729;
    1898: 710;
    1888: 266;
    1878: 181
