The ‘Moscow Libraries’ book search and online reservation service works as an electronic showcase, which presents all the books of the city’s libraries — more than 14.5 million items (fiction and scientific literature, periodicals, textbooks, etc.). Readers can find out which library has the books they need and make a reservation online using the service. To use the service, users will need the universal library card and a standard mos.ru account.

Users can search for the necessary items by title, author, publisher and other parameters. The service will show all libraries where they are available on an interactive map, and will show the address, phone number and opening hours, and the quantity of books available for online reservation.

Thematic collections for adults and children are regularly published on the main page of the service. There users can also learn about new arrivals in the libraries.

Users can reserve several books at once. The order will be prepared within three days, after which the user will have another three days to pick it up at the library. Users of the service can also receive information about the status of book reservations in the form of push notifications in the 'Moscow Public Services' app. Readers can save the books they like in the ‘Favorites’ sections in order not to lose them and return to the reservation later.
