Portable Document Format (PDF) is an increasingly popular standard for e-books (and hundreds of other uses) because of how well it preserves formatting across many platforms. The most robust tool for creating PDFs is Adobe Acrobat (which starts at $299.) For cheaper alternatives, try Adobe’s online convertor or pdfFactory. Both let you try before you buy.
