The Non-coding RNA Databases Resource (NRDR) is a source of data related to over 220 non-coding RNA (ncRNA) databases available over the internet. Our ncRNA Databases Resource tries to represent an updated source for databases information retrieval. It is part of a review with the aim of surveying all ncRNA databases available.

Our goal is to facilitate researchers' access to ncRNA information freely available on public databases. Our tool makes it possible to filter the sources and to find where the data of interest is stored.

We use four categorizations to help researchers quickly find the information they need: (a) RNA family; (b) Information content; (c) Information source; and (d) Search methods.

All above-mentioned categories can be used and combined for searching with the tool. Additionally, the user can filter searches according to different species (using scientific name), databases with data available for download, or those with a genomic overview (e.g. Genome Browser) of the available data.

For a complete description of this web tool, see our paper describing this survey:
