Funny enough -- after all the work and heartbleeding authors put into their work: it usually comes to an end when starting the bibliography ...
Self-made bibliographies are usally a mess -- inconsequently styled, full of mistakes and wrong citations! :-((( -- which isn't eased by journals and other publishers, each of which has its own citation style/system ...
I consequently ask my authors to use a reference managment programs, two of which I list here -- both have their own individual advantages and disadvantages, therefore each should be tested which suit best...
Both programs are more or less BibTeX based but import and export to the major reference datbase formats:
1. Citavi : Windows based program, now with English localisation.
Commercial programm, but not expensive, campus licences and a free testversion available.
Quote from the web-page:Search over 4000 databases and library catalogs
Add books automatically by ISBN and journal articles by DOI
Built-in preview for PDF, text, image, and multimedia files
Publish in over 600 citation styles
Organize knowledge: save quotations, thoughts, and comments
Plan and track tasks
Collaborate in a team
2. JabRef: Java program -- Platform independent.
OpenSource. GPL Licence.
The internet search isn't as good as citavi but the general handling is a bit easier, works quite well with OpenOffice.
