Last year's refurbishment of the Science Library necessitated a reorganisation of the journals which are housed there. As a rule of thumb, the last ten years (1991 -) of most titles can now be found on floors 1-4 whereas older (pre-1991) journals are either kept on the Ground Floor or in the Library's Store in Wickford, Essex.
Two other considerations are worth bearing in mind however:
The pre-1991 journals on the Ground Floor have been selected by UCL departments on the basis of importance. A list of which titles are there and which are in the Store is available at the Enquiry Desk.
Further information is available from the Head of Periodicals.
