This work discusses the terms library - user - librarian, as well as the need to study how the users' needs are met by the library services. If we stick to the first principle of librarianship by Donald Urquhart - "Libraries are for users" and his argument that many librarians accept this principle, but do not know how to find out whether their libraries truly meet the users' needs, we are aware that it is in the interest of the institution to find out to which extent users are satisfied with the services of our library. There are several research methods which can be used to get the answer to a great number of questions about wishes and needs of real and potential users of the library. One of the methods is surveying, that is conceptualisation of survey questionnaires designed for users. All of the survey research has the common basis: demanding answers from the representative population sample at the certain time point that is in as short period as possible. The questions for this survey questionnaire were prepared by a librarian who anticipated the number of questioned users, the time during which the survey is to be carried out as well as the places in the City and University Library Osijek at which the survey will be carried out. The survey questionnaires will be handed to the users personally when arriving in the library. Beside assembling of the basic data about users and evaluation of the library achievements and acquiring of the proposals for improvement of library work, the most important goal of the survey will be the acquirement of return information from users about the level to which their needs for library services are met and the level of familiarity with the types of services that this library is offering.
