This page has multiple references to the relevant resources at the Internet in the topics similar to our sections and individual pages. If you get across some useful sources that we should list at ASDN, we will appreciate if you let us know about these sources whether it is your own web site or someone´s else. We will also appreciate your comments about the quality of the pages we list as internet resources, particularly, if you find errors on some pages (including our own pages as well!) or if the link leads to a missing page. People move around and take their web sites to the new locations and some pages or servers may not exist any more.

Thank you for your support and collaboration!
