Using Data Repositories

"A data repository is a storage space for researchers to deposit data sets associated with their research. An open-access data repository openly stores data in a way that allows immediate user access to anyone. There are no limitations to the repository access."

Google Dataset Search

Did you know that you can use Google to find data?

You can search for specific file types in Google Search, for example, CSV files for datasets. By typing into Google filetype:csv in the search bar you are "telling" Google to only search for things that have that specific file type. For example: (water quality AND washington) filetype:xls will result in XLS (Excel) files mentioning Water Quality in Washington.
- Limit search results by web domain by typing into your Google search: site:.gov. This will limit datasets, files, etc. from specific websites. You could even do .org for professional organizations.
  - a sample search would look like this
Google also has a Dataset Search Tool. When using this tool you will only be searching for datasets by topic!
