Do you use Mendeley, Papers, Zotero or other bibliographic softwares that export their bibliography to bibtex .bib files for use in LaTeX with with bibTeX or bibLaTeX? Do you hate the way those bibliographic softwares generally export a .bib file that can’t exclude certain fields and so make a total ugly hash of your Bibliography Entries?
If so, then this Python script is for you! It deletes the extraneous fields in the .bib file leaving you with just the essential ones, like Author, Year, Title, Journal, etc. Never have a horrid bibliography entry with the article Abstract (!) copied into it ever again!
