What makes it different

• It's free.
  
• It's fast. You can download it from arXiv.org or its mirrors, just
  like preprints, without a trip to the library or bookstore or waiting for an
  order from the publisher.
  
• It's electronic. You can print it, but the PDF version has many advantages, like:

• Download it at work, home, etc. (or carry it on a CD), rather
  than carrying a book or printing multiple copies.
  
• Get updates just as quickly, rather than printing yet again.
  
• It has the usual Web links, so you can get the referenced papers just as
  easily.
  
• It has a separate "outline" window containing a table of contents on
  which you can click to take the main window to that item.
  
• You can electronically search (do a "find" on) the text.
  
• Save trees (and ink).
  
• Theft is not a problem.
  
• No wear or tear.
  
• No paper cuts.
