ABSTRACT: Online chemical databases are the largest source of chemical information and, therefore, the main resource for retrieving results from published journals, books, patents, conference abstracts, and other relevant sources. Various commercial, as well as free, chemical databases are available. SciFinder, Reaxys, and Web of Science are three major chemical databases that contain extensive search options. Herein, we review these three databases for their search effectiveness and interface. This comparison will be useful to the undergraduates, graduates, nonchemistry majors, researchers, and new librarians.

and materials in other platforms and delivers the information about the topic, author, abstract, publication name and type, and references.10 There are various types of databases: citation or bibliographic databases and full-text databases, as well as databases that contain chemical structures, chemical reactions, and chemical and physical properties.11,12 Bibliographic databases provide detailed information depending on the subject and scope of the information and are often linked to other databases as well as to the primary source. A full-text database is a compilation of documents or other information available for online viewing, printing, or downloading. In addition to the text documents in a full-text database, images are often included, such as graphs, maps, photos, and diagrams which are often searchable by keywords, phrases, or both.11,12 Chemistry databases can be considered search-specific due to how they vary in content and thus in the various ways they need to be able to search different information such as structures, reaction schemes, and synthetic routes. Different types of chemical databases are available: (1) Bibliographic databases for searching authors, subjects, citations, or full-text; (2) Numeric databases for searching factual or property information; and (3) Structure databases for searching molecules or reactions. Some databases such as SciFinder and Reaxys can be searched using bibliographic, numeric, and structure searching information.
hemistry is commonly referred to as the central science, and is used by many other scientific disciplines. If you ask someone working in the sciences how often they use chemical information, the answer is going to be very often. The search for chemical information using different databases is complicated and time-consuming; it would be nice to know prior to searching, which database might provide the most informative and relevant results for a specific query. For chemistry searches, commercial databases such as SciFinder, Reaxys, and Web of Science (WoS) and free sources such as PubChem and ChemSpider are available on the web. There are also resources available for keeping track of recent updates on chemical information sources.1 Numerous articles have previously described the coverage and features for SciFinder, Reaxys, and WoS separately, but none of them have reviewed and compared them head-to-head after major redesigns in their respective interfaces and functionality in recent years.2−9 In this article, we will provide a brief overview of the three major commercial chemistry databases: SciFinder, Reaxys, and WoS, and compare their search methods available, options for refining search results, technical specifications, and citation export features.
