The meta-information about preprints is entered the database of the electronic library of Keldysh Institute publications and then exported to external storages, such as eLibrary and CrossRef. To ensure the effective operation of search engines a site map of preprints is built. Additional efforts are made for the correct indexing of preprints by the Google Scholar search engine.
