HOW MY LIBRARY WORKS
Everything in my library is considered a file regardless of whether that "file" is actually a document, a web site link, a graphic, etc.

I provide a description or review of the file to help you decide if it's a file you might be able to use. I use the latest version of Adobe Acrobat Reader to create my PDF files, and in order to keep the size as small as possible, I don't make files compatible to earlier versions of Acrobat Reader. If you can't open a file, you probably just need to upgrade your Reader version to the latest version.

Some files are from third-party sources, so I have no control over how they created their files. If you have any problems, though, simply contact me.
