Do you need to find data for your research? We can assist you.
On this page you can find out about data resources subscribed to by UC Davis Library or about obtaining raw research data shared directly by scientists.
There are two ways to approach finding research data. There may be national or subject-level repositories that will contain the best match for the data you need. However, most of the times finding data cannot be accomplished by one-stop shopping. Data that do not have clear subject repositories are often hosted in general repositories or institutional repositories. To identify these, use registries–catalogs of repositories, searchable by subject keywords.
