There is a quality research facility within the House of Commons Library. It has to be impartial. I've long been a user of its publications - whilst working at Westminster - but also in my roles as a lecturer - and I always used to encourage students to use their publication.
They are freely available at https://commonslibrary.parliament.uk

In my programme PPS on the new internet radio station 'Spectrum on Air' I will be talking about the various publications - and why they can be of great use. My programme airs at Noon (UK time) on Mondays and 8pm (ET in the USA) on Tuesdays. Do listen in.
