Suggest Additional Literature
Many articles of this encyclopedia contain a list with additional literature at the end. If you can make good suggestions for such literature, we will be grateful to get them from you for example via e-mail. It is our goal to cite the best available literature for each topic.
Very different kinds of literature can be cited, for example textbooks, websites or PDF documents for download.
Please note that only high quality sources of information can be cited. The most important criterion is the usefulness for our readers. Important quality criteria are scientifically sound statements, understandable explanations in correct language, and in the case of websites a reasonable layout.
We do not list a source if this would primarily benefit the source itself rather than our readers. HTML links can be set, but they are implemented as so-called nofollow links, i.e., they do not serve to influence search engines. Paid links are also not accepted.
