During the period of time when a sponsor covers the maintenance cost of HandWiki, a logo of the sponsor with the URL link to sponsor's web page will be added to all HandWiki articles (at the bottom panel).

HandWiki Membership

HandWiki registration is free for researches with verifiable professional credentials, i.e. if the authorship in peer-review journals, books etc. can be established using the ORCID iD.svg ORCiD iD. If you do not have the ORCID iD.svg ORCiD account, but you think you are sufficiently qualified to edit HandWiki, you may use the verification form. Your credentials will be reviewed and you will receive a verification code. However, this may take some time.

If you are not a scholar, consider to become a HandWiki member. During the registration we kindly ask you to donate small amount of money. Your contribution will support the administrators who will activate your account, and who will monitor your first steps as a HandWiki author. It is also used to improve the speed of the HandWiki website, to support the administrative cost of its content and will help fight spam.

If you cannot register with ORCiD but still want to contribute to HandWiki, use HandWiki sandbox to create test articles.

HandWiki allows adding non-intrusive image Ads with an external "dofollow" URL link at the ends of HandWiki articles. Such Ads can target the audience for thousands of articles in specific HandWiki topics, such as Software, Physics, Biology, Chemistry, Engineering etc. (16 topics).

The image for Ads should follow these requirements:

  • Should be prepared in the PNG/JPEG format;
  • No animated images inside the icon;
  • The standard size of the icon is 120x90px;
  • The white (or transparent) background for the image is preferred.

The image should be prepared by the advertising side (or by the HandWiki team in exceptional cases). Such Ads will go directly to the HandWiki support, therefore, one can use the word “Supported by”. Examples of such Ads images are shown at the bottom of this page. Here is an image template which can be re-used for your purpose.

Use the HandWiki wizard to calculate the price and submit your advertisement:

Unlike many advertising resources, HandWiki's advertising features are maximum transparent for the users. The price per month is estimated from the number of independent HandWiki visitors. Before requesting advertising, please use the above link for cost estimates.


Please contact handwiki[AT]jwork.org for any questions related to technical support, user support and spam removal. Requests to add or edit articles will not be processed since HandWiki does not have editors who correct all articles.
