Similar to refining your search results, you can use the filters on the left-hand side of the Browsing Collections page to sort through the many primary sources in the World Digital Library collection. For example, if I'm researching the history of 18th century China, I can use the date filter on the left to just limit my search results to only show primary sources created between 1700 and 1799, and then apply an additional filter of location, China. This will show me the materials in the World Digital Library collection that are related to 18th century China. From here, I can further refine this browsing list of primary sources by format, by decade, or by specific location in China. When you find a primary source that you'd like to view in more detail, click on its title. This will take you to the source record, which will give you background information and citation details. Here I learned that this is not just a single map, it's actually 20 images in sequence. I can click on the image viewer to see all of the different images associated with this primary source, and then click on individual images to navigate through this source. World Digital Library is a great starting point for finding primary sources related to different topics and time periods in global history, and it's especially great if you're researching topics other than western history or european history.
