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? ;-)
Other Interesting Resources
||The operating system I use on my computer. One of the most well-known and reliable distribution of GNU/Linux free operating system.
||An anti-virus software I have successfully used for many years :-)
||A very convenient Finnish Web site with weather forecasts for many places all over the world (interface in English, Russian and many other languages).
|Free Historical Society
||A professional association of Russian historians.
||A BitTorrent tracker. Here you can find new software and movies deleted from RuTracker.org (interface only in Russian).
||A collaborative filtering recommendation system for books, movies, etc., that seeks to predict the “rating” that user would give to an item he or she has not yet considered, using a model built from that user’s social environment (in Russian).
|Institute of Scientific Information for Social Sciences (Moscow)
||An institute where I work :-)
||One of the few really independent newspapers that still exist in Russia.
||The largest BitTorrent tracker in Russia, former torrents.ru (in Russian).
||Schedules of trains and plains, ticket booking etc. (in Russian).
