Just recently I realized again how nerve-racking it is to adapt manuscripts to the tiny and picky formatting of various journals. To ease-up the process for some of you I uploaded here some .bsts I created throughout my PhD years.
The file is also available in the download section of my webpage.
If you care to write your own .bsts I can recommend makebst. Simple and straightforward tool to create citation styles for TeX.
PS: I did not create the APSR.bst. I downloaded it here and omitted urls.
