acroread, evince, xpdf, and kpdf are all file viewers capable of viewing PDF files. All of them allow you interactively to extract text from the PDF file.
■ acroread: Has a text selection tool on its toolbar that enables you to select text with the cursor and copy it and paste it into another application.
■ evince: Allows you to select text simply by running the mouse cursor over it. Choosing Copy from the edit menu will then allow you to paste it into another application.
■ xpdf and kpdf: Similar functionality; you can select rectangles of text with the mouse cursor and paste them elsewhere. This can be a very convenient way of getting text out of a PDF file, particularly if it is a complex one with a number of columns or separate boxes of text.
