Sorry for my trivial question but I am curious to know how many \documentclass exist. I use generally, article, standalone, book, report, beamer, but I see in many question also other \documentclass like \documentclass[runningheads]{llncs} or other forms.
I did not find a complete list of all existing
\documentclassand what are their function. Is there a complete collection where I can understand the significance and the output?
\documentclasses available is not possible, as new ones might be created as we speak. :-| – Werner Feb 22 '21 at 21:12
