To support the public availability of gene expression data, NCBI has launched the Gene Expression Omnibus (GEO), a repository for expression data from any organism or artificial source. Many types of gene expression data from platforms such as spotted microarray, high-density oligonucleotide array (HDA), hybridization filter, and serial analysis of gene expression (SAGE) are now being accepted, assigned accession numbers, and archived as a public data set. A series of precomputed definitions and descriptions of the data, as well as online tools for interactive retrieval and analysis, will follow. Visit the GEO project page for updates and further details at www.ncbi.nlm.nih.gov/geo/. —AL, DW
