The National Center for Biotechnology Information (NCBI) is a division of the United States National Library of Medicine (NLM) at the National Institutes of Health (NIH). It was established in 1988 to develop advanced information systems for managing biomedical data. NCBI provides a wide range of resources for researchers, healthcare professionals, and the public, focusing on genomics, molecular biology, and related fields.

One of the most widely used tools provided by NCBI is the Entrez retrieval system, which allows users to search across various databases simultaneously. These databases include PubMed, a comprehensive bibliographic database covering biomedical literature, and GenBank, a repository for nucleotide sequences. Other key resources include the Protein Data Bank (PDB), which stores three-dimensional structural data of large biological molecules, and the HomoloGene database, which provides comparative genomics information.

NCBI also offers tools for data analysis and visualization, such as BLAST (Basic Local Alignment Search Tool), which helps users identify similar sequences in genetic databases. Additionally, the NCBI website provides educational materials, including tutorials and documentation, to help users effectively utilize its resources.

The organization collaborates with international partners to ensure the accessibility and utility of its databases. NCBI’s mission is to advance scientific knowledge by providing high-quality, freely accessible information resources. Its work supports research in genetics, molecular biology, and related disciplines, contributing to advancements in medicine and healthcare.
