{\PDF\ files both to print and to read on screen} {Kaveh Bazargan} {\PDF\ started life as a reliable format for distributing a document for printing. In the electronic age when most documents are never printed, many people have predicted the demise of \PDF, in favour of other formats such as \EPUB. But \PDF\ has remained resilient and is likely to remain so for the foreseeable future. However, in general, a print \PDF\ is not ideal for reading on screen, and vice versa. So publishers either compromise, by putting minimal links and enhancements, or by producing two completely separate \PDF{}s. I will present methods by which we can use \TeX\ to create \PDF\ files that print perfectly, but that are enhanced for online reading too. }
