Online LaTeX editor for collaborative editing, great for Maths or Sciences. Many resources on the site too, including templates, help-guides, and links.
This document tries to show some possible solutions for creating screen based presentations. Most of the listed solutions are LaTeX-based because I personally prefer LaTeX - and derived tools - over other documentation systems.
HTML LaTeX equation editor that creates graphical equations (gif, png, swf, pdf, emf). Produces code for directly embedding equations into HTML websites, forums or blogs. Images may also be dragged into other applications like Word. Open source and XHTML compliant.
This database provides style files (bst and sty) for use with LaTeX documents using BibTeX or AMSrefs to manage the bibliography. The styles are referenced by the academic journals to which they apply.
LaTeX is a high-quality typesetting system; it includes features designed for the production of technical and scientific documentation. LaTeX is the de facto standard for the communication and publication of scientific documents. LaTeX is available as free software.
LyX is a document processor that encourages an approach to writing based on the structure of your documents (WYSIWYM), and not simply their appearance (WYSIWYG).
LyX combines the power and flexibility of TeX/LaTeX with the ease of use of a graphical interface. This results in world-class support for creation of mathematical content (via a fully integrated equation editor) and structured documents like academic articles, theses, and books. In addition, staples of scientific authoring such as reference list and index creation come standard. But you can also use LyX to create a letter or a novel or a theatre play or film script. A broad array of ready, well-designed document layouts are built in.
