            my $key     = $enty->key;

Note: You can also change the authors with $entry->field('author', $authors_string)

to_string ([options])

Returns a text of the BibTeX entry in BibTeX format. Options are a hash.

"canonize_names": If true (the default), authors' and editors' names are translated into canonical bibtex form. The command "$entry->to_string(canonize_names=>0)" overrides this behavior.
"field_capitalization": Capitalization of the field names. Can take values 'Uppercase', 'Lowercase' (the default) or 'Titlecase'
"print_pre": False by default. If true, the text in the Bib file before the entry is printed. Note that at present we assume the text before the entry NEVER has the @ symbol inside
