In order not to make the list too long, I only give here links to those resources that I use more or less regularly myself, except well-known ones :-)
Searching the Books in the Internet
||An electronic library of academic and technical literature, reference books and educational materials, one of the largest electronic libraries in the Russian Internet.
||An on-line service for downloading articles from academic journals (in Russian).
Resources about J. R. R. Tolkien and His Works
|Tolkien Society of Saint-Petersburg
||The most famous and rich one of Russian resources devoted to the fiction of J. R. R. Tolkien and to the Russian Tolkien fandom. New materials are added very seldom in recent years, unfortunately.
||Rather a new Web site with a good collection of articles and translations; new materials are added regularly (in Russian).
|Tolkien Texts Translation
||An informal association, specializes in professional translation of works by J. R. R. Tolkien, first of all of the drafts (in Russian).
||A commercial server, all the updates are made by employees of the 2GIS company. Very good maps, a lot of information about organizations in each building. The only problem is that the 2GIS maps cover only those cities where there are branches of the company.
||A popular cartographic wiki server. Unlike WikiMapia, is focused on making an electronic topographic map of the world. OpenStreetMap is especially useful if you are interested in information about somewhere in the country.
||An open-content collaborative mapping project that aims to mark and describe all geographical objects in the world. Are you sure you know everything about your town/neighbourhood? ;-)
