    abstract = {The NCBI Gene Expression Omnibus (GEO) represents the
      largest public repository of microarray data. However, finding
      data in GEO can be challenging. We have developed GEOmetadb in an
      attempt to make querying the GEO metadata both easier and more
      powerful. All GEO metadata records as well as the relationships
      between them are parsed and stored in a local MySQL database. A
      powerful, flexible web search interface with several convenient
      utilities provides query capabilities not available via NCBI
      tools. In addition, a Bioconductor package, GEOmetadb that
      utilizes a SQLite export of the entire GEOmetadb database is also
      available, rendering the entire GEO database accessible with full
      power of SQL-based queries from within R.},
