I'm pleased to announce the publication of the online Guide to US History Sources, on the Bodleian Libraries' LibGuides site. This guide replaces the old yellow paper versions which used to be available in the library, and provides links to and information about a whole variety of resources available for research in US History.
The web address for the guide is http://ox.libguides.com/ushistory. The benefits of an online guide are that the links to e-resources are active (if you're not connected to the University network you will need to sign in on SOLO first), and the guide can be easily and frequently updated. Hopefully it will provide you with an excellent starting point for your research. Please feel free to make suggestions about more resources to include, or if the guide could be made more user-friendly. We also have a separate online guide available for US Government Publications, and could potentially create further specific guides in the future.
The online guide is designed to be complemented by the US Studies Resources at Oxford blog, which will go into more depth about individual resources and topics. I'm also always happy to help you if you have questions about resources available either in the library or online.
