Do you use LaTeX? It is a wonderful text creation system, often used for scientific publications but useful for much else as well. The results are so ridiculously beautiful it's almost jarring whenever you see a normal word processor document next to the LaTeX version.
LaTeX comes with good support right out of the box for basic document styles. And if you write a research paper, the conference or journal will often have a predetermined style file you simply download and use. But for many other things it can be difficult to get a good document design — you'll have to search the web for scattered style files and examples, or try to design it yourself with predictably lousy results.
LaTeX Templates is looking to change that. It's a collection of high-quality template documents ranging from theses, to CV and cover letters to calendars, notebooks and reports. It's not a large collection yet, but what is there is of high quality and promises to grow over time.
You can use a document template as-is, or tweak it anyway you want. Or use them for inspiration and tips on how to achieve special typographic tricks in LaTeX without spending hours looking all over the net.
