The Rise and Fall of the Initial Era

TL;DR

This paper investigates the rise and fall of the Initial Era, a historical period when scholarly authors frequently used initials rather than full names. Using Dimensions data, the authors classify author-name forms across papers, authors, countries, and disciplines, employing an epochal framework that treats pre-1945 as anecdotal and post-1945 as statistical. They identify three eras—Developmental Era (1665–1950), Initial Era (1945–1980), and Modern Era (1980–present)—and document how technological changes (DOIs, Crossref, PubMed, and ORCID) and globalisation have driven a rapid shift from initial to full-name usage, with notable regional and disciplinary variations. The study discusses implications for gender visibility, provenance, and future bibliometric archaeology, highlighting data-coverage limitations and proposing directions for richer demographic metadata and alternative identity representations to support transparent, trustworthy scholarly records.

Abstract

Bibliographic data is a rich source of information that goes beyond the use cases of location and citation -- it also encodes both cultural and technological context. For most of its existence, the scholarly record has changed slowly and hence provides an opportunity to gain insight through its reflection of the cultural norms of the research community over the last four centuries. While it is often difficult to distinguish the originating driver of change, it is still valuable to consider the motivating influences that have led to changes in the structure of the scholarly record. An "initial era" is identified during which initials were used in preference to full names by authors on scholarly communications. Causes of the emergence and demise of this era are considered as well as the implications of this era on research culture and practice.

• Figure 1: A page from the Philosophical Transactions of the Royal Society from December 1669 demonstrating at once the similarity to a modern research article and the significant differences in the level and detail of metadata present in the article noauthor_letter_1997.
• Figure 2: Development of averages of co-authorship numbers on academic output since 1665. The red line shows the modal number of co-authors, the yellow line shows the median number of co-authors, the blue line shows the mean average number of co-authors. The grey shaded area shows the standard deviation from the mean cutoff by the zero axis.
• Figure 3: Number of papers in each year with more than 100 (yellow area), 500 (blue area) and 1000 (red area) co-authors respectively.
• Figure 4: Volume of scholarly publication using the restrictions specified in Listing 1 for comparability with other plots in the paper. This plot shows a clear cutoff around 1940 at which point there is sufficient data for the reasonable interpretation of statistical approaches.
• Figure 5: Proportion of papers in which all authors state their names using initials ("Initial form %" - red line), versus all authors stating their full names ("Full form %" - blue line) versus some authors stating their full name while others state their initials ("Mixed %" - green line. "Undetermined %" includes edge cases that we have not programmed for including no first name or no name at all. We note four distinct eras of behaviour: The Developmental Era tracks from the genesis of scholarly publication until 1945; The Initial Era from 1945 to 1980; and the Modern Era from 1980 to present day.
