### APA-href package

This is a slightly tweaked version of the APA style that is provided with biblatex (biblatex-apa). This package is just a collection of code snippets available online, with minor modifications. The hyperlinks work both with the authoryear citestyle, as with apa's own citestyle.
• The main feature is that hyperref links now include the author names. I got most of the code from this source.
• A 'possessive cite' command, \citeposs, that supports multiple years.
• Small style tweaks for the bibliography (with the option apachange): new style for incollection, 'editors' in small-caps, new style for thesis, new format for page numbers.

Here is a small example of what your preamble would look like:

\documentclass{article}

\usepackage[american]{babel}

\usepackage[backend=biber,style=apa,%
citestyle=authoryear,uniquename=false]{biblatex}
