Duplicate detection algorithms of bibliographic descriptions

Purpose – The purpose of this paper is to focus on duplicate record detection algorithms used for detection in bibliographic databases.Design/methodology/approach – Individual algorithms, their application process for duplicate detection and their results are described based on available literature (published articles), information found at various library web sites and follow‐up e‐mail communications.Findings – Algorithms are categorized according to their application as a process of a single step or two consecutive steps. The results of deletion, merging, and temporary and virtual consolidation of duplicate records are studied.Originality/value – The paper presents an overview of the duplication detection algorithms and an up‐to‐date state of their application in different library systems.
