Getting Bibtex formated references

Adding references to a thesis work is often a vexing  and long work. A nice solution is proposed by: http://www.mendeley.com/; you give the article title and the website generates the reference for you. Several reference format are available such as:

• APA,
• BibTeX,
• Cell,
• Chicago,
• Harvard,
• MLA,
• Nature,
• Science. 

Have a look it is worth it! And free...
