After a lengthy closure for redevelopment, the Central Library reopened about 3 weeks ago. I had a chance to look round today, and I think it has been worth the wait - the County Council has done a really good job. The layout seems very clear and welcoming, and as might be expected as well as the books, there has been a significant investment in IT with computer terminals and free wi-fi access to help those who want to use the library for studying. Judging by today, it already seemed to be very popular.
More details available from the library's website http://hipweb.cambridgeshire.gov.uk/central/ or visit yourself - the entrance is from the first floor of the Grand Arcade, and the library is now open seven days a week.
