Do not expect to find what you are looking for. The way I do it, is to look for stuff, if I find anything that is of interest I will download it and keep it organized for a latter time. I know that might sound too efficient, however I have experienced many sites that are of temporary nature that have good information. It could also be that some information is only placed for a limited time. In the age of dial up connection to the Internet, it is easier to find it on my hard drive rather than dial up and look for it again.
Bookmarks tend to grow astronomically and out of control.
They lose their use once they go above a certain number. You will soon need your own search engine. So I have created a font based on it that can be used for transliteration. Included in the zip file is another font that has the most often used Islamic phrases in a calligraphic style, in Arabic of course. Their origin is long forgotten by now, I have used them font for my own purposes.
