I began my academic career specialising in voting behaviour in the House of Commons, in particular intra-party dissent by Members. This entailed manually checking every division list. For my doctoral research, I estimate I read over 3,000 division lists, with the number of names running into seven figures, in order to identify any Members voting against their own side. I also variously had to check the division list in Hansard with the figures recorded in the Votes and Proceedings: the latter provided the definitive list and that was not always the same as that in Hansard.
How times change. Nowadays, proceedings, including division lists, are available online. Not only that, but in the Lords we have started utilising electronic means of recording votes, with the consequence that the breakdown of how peers have voted can be published once the division has finished. It used to be the practice when voting to give your name to one of the two clerks in the division lobby: each clerk had the list of peers’ names and would cross your name off. The lists were then electronically scanned and the results published online. The process is now even quicker. There was a trial period where our names were recorded in the usual manner, but we then had to give our names to another clerk who had a tablet device and who recorded our names electronically. Now, there are just two clerks with tablet devices. As soon as you give your name, the clerk taps it on screen and your vote is recorded.
You can get the breakdown of divisions online here. Had such a facility existed when I did my original research, life would have been much easier..
