When I visit web sites I notice many of them are offering e-books. These are usually books in a PDF format that can be downloaded and viewed with a reader. The most popular reader is Adobe’s Acrobat Reader. The once nice thing about PDF documents, and probably the reason they were chosen for e-books, is that the document will look the same regardless of the reader’s computer. Other formats, such as Microsoft Word, may look different depending on whether the reader has the same fonts installed.
