Obviously, the internet has given us access to far more knowledge than ever before. Obviously, though, that information isn't always reliable. So, from a historians perspective, do you find it easier to find the information you need by searching the internet or using traditional methods of finding sources? ie: from a library or some other repository of written sources.
It's made my job a whole lot easier personally. Primary sources are the cornerstone of writing history and the internet has made finding them a whole lot easier in my case. I'm studying WW1 and the places that hold the papers I need all have websites now, usually with pretty good search functions for their collections. Search functions and databases of catalogs are vital for not just finding material, but for being able to see what exists.
Digitisation is the other big thing that's been helping historians. When archives and libraries get the money to do so they've been scanning and uploading some of their collections. The Australian War Memorial for example has digitised all of the Australian WW1 War Diaries, General Monash's papers, General Birdwood's papers and so on. This means people from all over the world can access and use this material without the need to fly to Canberra and spend days or weeks trawling through tens of thousands of pages of documents.
I think students often fall into the trap of using.... unreliable sources, but historians I think are usually pretty good with not getting caught by them.
