From the U.K. National Archives:
The National Archives has launched a set of more than 60 'research signposts' on Looking for records of a person, to simplify the process of researching an ancestor. Each signpost takes a single topic - for example the census, railway workers or the Indian Army. The short, clearly written guide points you to the most useful resources, whether these are online or original documents, held at The National Archives or elsewhere.
