Linking to a page within a PDF
Linking to a PDF on a web page is easy enough:
<a href="mypdf.pdf">This is my PDF</a>
Not until Acrobat 7.0 came out could you link directly to a page within a pdf, such as sending someone to page 4 of the PDF to skip straight to the pertinent content.
<a href="mypdf.pdf#page=4">This is my PDF</a>
Note: This feature only exists in Adobe’s Acrobat product, but I don’t see it being much longer before an Open Source PDF Viewer will implement this feature.
