Everyone loves free document templates and vector art, so here are a few. I posted some vector artwork I created in Adobe Illustrator to my Downloads page. I use those designs in many of the technical manuals I wrote in my career and decided to make those available to anyone who can make use of vector artwork.
I also made available many of the Microsoft Word document templates I developed in my career. Some I designed back in 2000 and recently updated, so they are pretty solid in their use assuming you understand and know how to use document styles.
I use all the files posted on the Downloads pages on both PC and Mac versions of Adobe and Microsoft applications. Check them out and use freely to create your content.
