I like to write academic research paper on my iPad. But I realize there is no app that allow me to tract all my citations... I am talking about writing a paper where you have more than 100 references and you need to tract them, not lumping them all together. For example: S. Job is one of the founders of Apple.1 He likes to wear a shirt.2 He also wears glasses.3 References: 1. News from macrumor 1999. 2. News from macrumor 2001. 3. News from macrumor 2002. Is there any iPad app that can do such a thing?
