Instructions for Authors of SBC Book Chapters
This meta-paper describes the style to be used in articles and short papers for SBC conferences. For papers in English, you should add just an abstract and for the papers in Portuguese, we also ask for an abstract in Portuguese ("resumo''). In both cases, abstracts should not have more than 10 lines and must be in the first page of the paper.

LaTeX ePub / eBook Template
This document shows how you can get ePub/eBook-like formatting in LaTeX with the memoir document class. You can't yet export directly to ePub from writeLaTeX, but you can export to PDF. To get ePub, you can download the LaTeX source from writeLaTeX and run it through a format conversion tool, such as htlatex to get HTML, and then go from HTML to ePub with a tool like Sigil or Calibre. See this thread on Stack Overflow for more advice.

Science Textbook Template
This template is for a science textbook. The license is Creative Commons Zero v1.0 Universal.
The template originated from the author's search for a professional textbook style with the same level of quality as the most "elegant" looking books in his own library of math and computer science books.
This search ended when the author realized that the default latex book style produces the same style he was looking for. That style is exemplified by the classic computer science textbook "Compilers: Principles, Techniques, and Tools", also known as "The Dragon Book".
The goal of this template is provide a minimal working example of a large textbook in the default style so you can see, for example, what a Table of Contents or an Index spanning multiple pages will look like. Please view the compiled PDF.
