In 2006, a handwritten diary by Misirkov written during his stay in Russia in 1913 was discovered. It was declared authentic by Bulgarian and Macedonian experts and was published in 2008. The content of the diary clearly shows that at the time, Misirkov was a Bulgarian nationalist. It has given rise to new public discussion over Misirkov's stances on Bulgarian and Macedonian ethnicity. The manuscript, includes 381 pages written in Russian language.
