Many libraries in the UK have free access to many of the genealogy sites, including Ancestry and Findmypast (who at present hold the complete 1911 census records for viewing).
But some will only have access to 1911 census for free for a limited amount of time and viewings. This happened last year in some libraries.
So check with your local library to see what sites they have access to and if it is free for a limited period.
Also some libraries do require you to book your hour in advance and you cannot afford to be late and if in a popular library, you will only get your 1 hour and no more as someone else will be waiting.
Advice - make a list of what you want to look up and if possible take a USB stick and save all your findings to this to take home to look at on your own computer at your leisure. Also always take some notepaper and pencils (not pens -frowned upon by most places) and ENJOY
