One accompanying phenomenon of modern science, which is focused on (measurable) output, is a radical increase in the types and forms of plagiarism, or fraud in other words, at the level of student essays, dissertations and pure research studies. This contribution demonstrates that cases of fraud, being both exemplary and the most serious ones in terms of financial implications, occur in the natural sciences, medicine and technological sciences, yet the humanities, namely historiography, are also blighted by misconduct of a similar vein. The author lists exemplary cases of fraud in academic research. Thereafter, supported by the Codes of Practice of the Academy of Sciences of the Czech Republic and the Charles University, he identifies with the help of exemplars, the four fundamental types of academic fraud in publishing: plagiarism, fabrication, falsification (including “negative falsification”) and data theft. He also highlights the fact that these are not mere trivial offences nor marginal phenomena but rather significant breaches of scientific conduct with an impact on the very substance of the respective discipline, and thus present a serious problem that modern historiography needs to address.
