Can social networks ensure better awareness of library patrons? If so, then to what extent and in what way? It is vital to choose the right channel, the right social network. Can the awareness of patrons be increased? Can social networks contribute to that? What are the specifics of information distribution in social networks? The way in which information is distributed has changed. From a letter, through telephone, email, sms, we've come to the era of social networks, while the former means of communication haven't vanished. The difference is that most of today’s society is online 24/7. It's a completely natural development of our society and it forces libraries to change their ways of providing services. -- The process of information distribution has to be managed and guided to the appropriate groups of patrons. Without this, the result will be a dissatisfied library patron who has a profile on one of the social networks. An unmanaged flow of information influences patrons in negative ways and together with the usage of electronic communication (in this case social networks) can enhance its disadvantages – for example, by rumors. Libraries often battle against the passivity of the younger generations towards books and the library itself. Young people are drawn to new things (for example smartphones) and a library can use this to its advantage. It is vital to find a way to our patrons through their interests, likes, programs and gadgets they often use and to know where they spend most of their free time. -- The new era of Internet with social networks in the forefront is also drawing nearer to a book (for example social networks BookFan or Shelfari), so why doesn't it draw nearer to a library? Social networks and other new media or technologies are changing the way we percieve libraries and their services. Social networks are connecting various types of users, that's why a “modern library“ can't go without being involved with social networks. They are a new concept of information distribution, but they also require active participation from a patron.
