In the days before photocopiers, getting hold of an offprint from the author was a useful way of getting a copy of the text, tables, images and formulae of a scientific article without having to copy it by hand from a library volume. The ways in which offprints circulated – whether requested by authors in locations where the journal was not available, or distributed strategically by the author to people s/he wanted to impress – is an intriguing element of the sociology of scientific communication.
The history of offprints also illustrates the long history of out-of-commerce circulation of scientific knowledge. Even when the issues, parts or volumes of the published journal were available for public sale, authors could send their private supply of offprints to colleagues, friends and potential sponsors. This long tradition still holds true in the digital world, when printed copies have been replaced by PDFs, but most publishers will still supply authors with a PDF for circulation through their networks.
As well as providing an out-of-commerce route for circulation, offprints also (in certain historical periods) provided a route for more rapid circulation. They were originally available more quickly than the collated issues or bound volumes of the journal in which the article formally appeared.
In this post, we will discuss what the Royal Society’s archive can reveal about the history of offprints.
