- Access to obscure and arcane information. Because there are so many people with such diverse interests on the Internet, a search can often turn up the most unusual and hard-tolocate nugget of data.
- Access to digitized versions of primary sources. Some libraries are digitizing (making electronic versions) of primary research sources such as personal letters, official government documents, treaties, photographs, etc. and making these available for viewing over the Internet. The same is true for audio and, in some cases, video.
- Access to searchable databases and datasets. There are many sites on the Internet where you can search a collection of statistical data, such as demographic or social science data. While some databases on the Internet are fee-based, others are free.
