Adobe Reader is free. It is also one of the biggest magnets for attack on your computer. In fact, it is likely only behind Adobe Flash and Oracle Java.

Researching needs hardwork and patience. And most importantly, the ability to read a lot of related subject matter to make better observations and inferences. Even when your research is 100% original, you will need a bunch of documents to quote and to support your hypothesis. Since most of the academic and research materials are now digitized into PDF files, your efforts are actually cut in half.

PDFs make sifting through tens of thousands of pages of documents easier and they are easy to carry around too. But, grouping together a bunch of PDF files into a library that can be searched and annotated is no easy task. That’s where ReadCube comes to the rescue.
