Information retrieval (IR) in computing and information science is the task of identifying and retrieving information system resources that are relevant to an information need. The information need can be specified in the form of a search query. In the case of document retrieval, queries can be based on full-text or other content-based indexing. Information retrieval is the science of searching for information in a document, searching for documents themselves, and also searching for the metadata that describes data, and for databases of texts, images or sounds.
DBLP is a computer science bibliography website. Starting in 1993 at Universität Trier in Germany, it grew from a small collection of HTML files and became an organization hosting a database and logic programming bibliography site. Since November 2018, DBLP is a branch of Schloss Dagstuhl – Leibniz-Zentrum für Informatik (LZI). DBLP listed more than 5.4 million journal articles, conference papers, and other publications on computer science in December 2020, up from about 14,000 in 1995 and 3.66 million in July 2016. All important journals on computer science are tracked. Proceedings papers of many conferences are also tracked. It is mirrored at three sites across the Internet.
The UKeiG Strix award is an annual award for outstanding contributions to the field of information retrieval and is presented in memory of Dr Tony Kent, a past Fellow of the Institute of Information Scientists (IIS), who died in 1997. Tony Kent made a major contribution to the development of information science and information services both in the UK and internationally, particularly in the field of chemistry. The name 'Strix' was chosen to reflect Tony's interest in ornithology, and as the name of the last and most successful information retrieval packages that he created.

The European Summer School in Information Retrieval (ESSIR) is a scientific event founded in 1990, which starts off a series of Summer Schools to provide high-quality teaching of information retrieval on advanced topics. ESSIR is typically a week-long event consisting of guest lectures and seminars from invited lecturers who are recognized experts in the field. The aim of ESSIR is to give to its participants a common ground in different aspects of Information Retrieval (IR). Maristella Agosti in 2008 stated that: "The term IR identifies the activities that a person – the user – has to conduct to choose, from a collection of documents, those that can be of interest to him to satisfy a specific and contingent information need."
Peter Willett is an Emeritus Professor of Information Science at the University of Sheffield, England.
