Providing free and open access to scientific literature and data 

Do you love biological data? Join NCBI in celebrating International Love Data Week, February 12-16, 2024! Love Data Week is an international celebration of data, which takes place every year during the week of Valentine’s Day. This year’s theme is “My Kind of Data,” focusing on data equity and inclusion, disciplinary communities, and creating a kinder world through data. 

NCBI is one of the largest sources of free and open biological data on the web with over 300 TB retrieved every day. There’s something for everyone to love! 

Find the data YOU love!  

You can find and access the following data through our website, APIs, command line tools, and FTP site. Easily analyze, compare, and download genomic data using tools from the NCBI Toolkit, such as NCBI Datasets, BLAST, RefSeq, and other sequence analysis tools – all part of the NIH Comparative Genomics Resource (CGR).
