A List of Some Web Data Sources

Well I needed to pull together a listing of publicly available data sources for a project, so I figured I’d post them here as well. Some descriptions and tag lines have been taken directly from the website, and some I quickly created on my own. This list is by no means comprehensive (I probably have about 100 links in the “Data” folder of my bookmarks…) but it’s a quick snapshot at some useful data sources on the web. That being said, there are a lot of considerations when targeting a data set and tomorrow’s need for data will most likely differ from today’s need for data. Build and execute a target data strategy using the vast sets of search engines, libraries, and social networks on the web and you’ll be just fine.
