I have created PDF file versions of some of my more popular articles.
These files provide a clean version of the posts – that is, they don't include the sidebars and ads and other clutter you end up with when you print the articles from a browser. This provides an easy way to distribute copies of these articles (electronically, or printed), in a very presentable format. I hope you find these useful.
Feel free to download, print, and distribute these files as you wish.
I also recently added a “Print Post” tool that makes it easy to print any post on the site without the sidebars and menus, so feel free to use that as well (see “Print This Page” at the bottom of each post).
