Each page and the site avoid JavaScript to support navigation. If it is deactivated minor disadvantageous effects will occur, however, the single pages will be accessible so far. The site is designed for working either with or without JavaScript.
The site is created on a PC with present virus checking software and is hosted on a paid, advertisement free server or webspace, resp. Active contents are reduced to a minimum and will not be loaded without your explicit permission.

The site attaches great importance to the security interests of visitors. Any relevant visitor data input is not required.



Every site hit increments the counter with a latency. The following data acquisition takes place using JavaScript and possibly cookies: Provider, referrer and link counter. The information gained will exclusively be used to optimize the site. See under Popularity below to get an impression, which data are logged - and - what commercial interested parties (and much worse guys!) could even read out of your pure click. The site itself does not make any usage of cookies, trackers or similar techniques.

Each and any identification or any tracking of visitors are neither desired nor arranged.



Each of the given information, technical data, specifications and descriptions are determined by best effort and are proofed in different ways as far as possible. This is valid for listed software, too.

There is no guarantee for fault-free and complete information, descriptions, technical data, specifications and features of appliances and software.


Contents (Fair Use)

Extracts of numerous public and other sources are used by this site. Because the sources are cited and named as far as known and taking into consideration the non-commercial, sole informative character of this site and the small sizes of imported and displayed extracts the webmaster supposes that there are no violations against copyrights.
(As far as possible and necessary the original authors were asked to use their material. Besides all the sources are named and the contents are checked as far as possible.)

Nevertheless, if you are holder of a copyright or a trade mark in question and disagree with this (Fair Use) point of view, please contact the webmaster to come to an amicable settlement.


Intellectual property

Even now and then some text passages and images could be familiar to you: some users, especially commercial organizations inclusive print media, have made broad one by one use for their own publications. Of course, without any source reference and consultation. Only the Klett publishing company and a very few private individuals acted in an exemplary manner.
(Well, just to mention, the canon - the site and its major contents - existed before Wikipedia has come up.)

If you intend to use texts and/or images of WP's HP/frame set in private or not commercial field (e.g. education and science), you should neither alienate nor pass off these as own creation and a link, however, or at least a reference to WP's HP would be highly appreciated.

EU General Data Protection Regulation and more restrictive browser settings have made it rather calm down in respect to counter since May 2018 latest. And in fact I don't want to constrain it either. I'm just curious about whether server and site are running.
