1. KPDF 0.5.10 -†more than a reader
KPDF is a pdf viewer based on xpdf for KDE.
Being targeted to home users it has some very unique features to enhance your reading pleasure in addition of doing everything you can expect from it.
Adobe Reader has become the standard for reading ebooks and documentation online. For Windows, there are 3rd party readers like FoxIt that can be substituted, but on Linux, the best choice is still Adobe Reader.
3. Evince – Simply a document viewer
Evince is a document viewer for multiple document formats. It currently supports pdf, postscript, djvu, tiff and dvi. The goal of evince is to replace the multiple document viewers that exist on the GNOME Desktop with a single simple application.
4. GNU GV
GNU gv allows to view and navigate through PostScript and PDF documents on an X display by providing a graphical user interface for the Ghostscript interpreter.
gv is a improved derivation of Timothy O. Theisen’s Ghostview, originally developed by Johannes Plass.
Xpdf is an open source viewer for Portable Document Format (PDF) files. (These are also sometimes also called ‘Acrobat’ files, from the name of Adobe’s PDF software.) The Xpdf project also includes a PDF text extractor, PDF-to-PostScript converter, and various other utilities. Xpdf runs under the X Window System on UNIX, VMS, and OS/2. The non-X components (pdftops, pdftotext, etc.) also run on Win32 systems and should run on pretty much any system with a decent C++ compiler. Xpdf is designed to be small and efficient. It can use Type 1, TrueType, or standard X fonts.
Xpdf should work on pretty much any system which runs X11 and has Unix-like (POSIX) libraries. You’ll need ANSI C++ and C compilers to compile it. If you compile it for a system not listed on the xpdf web page, please let me know. If you can’t get it to compile on your system, I’ll try to help.
