Quickly sort out bibliography files for LaTeX.
Sorts the given LaTeX bibliography file into alphabetical order of the citekeys. The citekeys are given as author_year for a single author, author1_author2_year for two author papers and author1_ea_year for three or more authors. If there are more than one items with the same citekey, they are ordered by month and appended with a, b, c and so on. This makes it more readable when writing.
In the Examples folder an example of before, bibliography.bib, and after, bibliography_updated.bib can be found.
To run: python sortbibliography.py bibliography.bib [newbibliography.bib]
