Back at the end of August, the US Bureau of Land Management’s General Land Office website made some of its survey plat collection available online as searchable images that can also be downloaded. I finally had a few minutes to check it out, and this is a really useful resource if you are involved in research related to land titles, although not all the US states are represented in the current online collection. In addition to the survey plats, the site has copies of federal land patents, including images of the original documents, and users can also download certified copies of these documents for a fee. Most of the data are related to the 30 US states that are known as Public Land States, but there are some documents related to other states as well, and it looks like they hope to add more. If you are interested in historical land documents, definitely check out this collection.
