PDF Viewers That Are Open Source
Evince PDF
Evince is a document viewer for multiple document formats. The goal of evince is to replace the multiple document viewers that exist on the GNOME Desktop with a single simple application.
Evince currently supports PDF, Postscript, djvu, tiff, dvi, XPS, SyncTex with gedit, comics books (cbr,cbz,cb7 and cbt), and many more.
Sumatra PDF
A minimalistic PDF reader. Sumatra PDF has a minimalistic design, and its simplicity is attained at the expense of many other features. As is characteristic of many portable applications, Sumatra takes up little disk space - it has a 1mb setup file (compared to Adobe Reader's 27.5mb setup file), and it starts up rapidly. It was designed for portable use in the sense that it's just one file with no external dependencies so you can easily run it from external USB drive[1]. This would classify it as a portable application.
One interesting feature of Sumatra PDF is that it remembers exactly the last opened page for each pdf file. This helps it be a very useful pdf e-book reader.
Review: Sumatra PDF contains anti-features. It enforces DRM restrictions. As stated on a Sourceforge review, "it supports DRM of "protected" PDF files, and the author stubbornly refuses to make it optional. So you can't print PDFs for offline reading, and you can't copy text to the clipboard for pasting into Google translate, saving to your notes, quoting in a paper, etc."
