Gadget: PDF Markup Tool – PDF Xchange Viewer

PDF file format is almost a standard now for document sharing and for papers. This file format can be read using the reader provided by Acrobat.

Lately, I have been trying to read research papers on the screen so as to reduce the need of printouts. To do this, I feel like having a marker or a pen to mark on the document I am reading is very convenient. Although Adobe do provide “Acrobat Professional” for such purposes, it cost money.

These days, I have been using a free software called “PDF Xchange Viewer”. It is free even for commercial use. Of course, you get more features if you buy the software but the free version is good enough for my document-reading purposes.

You can find the software from the following link:

I also like the way it opens multiple PDF files — instead of instantiating multiple copies of the software (as for Acrobat reader), it open it in a tab format as in firefox. I guess this is more memory-efficient.
