For MLA format, you will need (not in this specific order) the authors name, date published, the publisher, and the ID of the book...
Honestly if you are trying to write a bibliography using MLA format, use easybib.com. It really helped me on my National History Fair projects. It's also very simple to use, and it can do books, online websites, newspapers, everything. It also does many other formats.
Using there imagination! they can just make anything out of the bloom, like "You look like a flying butterfly in the sunlight." being humorous and having that little magic touch.
