The digital environment, which greatly affects an individual’s daily life, requires constant access to personal information. Almost every one of our steps can be reconstructed by a combination of cookies, the IP address, search analysis and storage of queries on search engines, which is easily linked to our personal data. Because digital environments have "flawless memories," meaning that everything on the web remains available forever, there is a need for the right to be forgotten – the right of an individual to ask an organization/browser or another data provider to delete all personal information that it collects or stores about them, i.e. to remove from the search results all links that lead to data about that individual once there is no longer a legal basis for their storage and preservation. The exercise of this right has led to a new digital regime in which search engines decide which information is relevant or irrelevant; which is redundant and can be removed from the web or, on the other hand, which information is in the public interest, meaning it should stay on the web and remain available to the public. This thesis deals with precisely this issue - the impact of the application of the right to be forgotten on information retrieval in the digital environment. Special emphasis is put on striking a balance among the various rights that are indispensable factors within the very concept of the right to be forgotten, such as the right to privacy and freedom of expression and access to information. These issues must be decided upon by information professionals, including librarians. Information professionals must take all these rights into account when deciding whether to comply with requests to remove certain information from their data sources such as digital collections, bearing in mind that information institutions must adhere to policies ensuring unhindered access to information but also respect everyone's right to privacy.
