The study finds that London's chief librarians strongly support a move towards a single membership. A single card would provide greater flexibility and improved accessibility. However, it also notes that there are significant challenges to be met, including financial and technical implications, and the retention of the strong local identification and ownership that most libraries enjoy. The study provides a number of possible ways forward as options for discussion.

Culture Minister David Lammy said: 'I am pleased that the feasibility study recommends that a single membership card should be pursued. London's extensive public library network is a valuable and important resource for all its citizens. Delivering this project will be immensely challenging, but the advantages for Londoners are clear, and I would be delighted to see it happen in good time for the London Olympics in 2012.'

Chris Batt, Chief Executive, MLA said: 'I am pleased that the feasibility study demonstrates the significant value of one public library card for London. It will encourage use and will widen access to the rich library resources available across the capital.'

Lyn Brown MP, chair of LLDA and of the All Party Parliamentary Group on Libraries and Information Management, said: 'This study has clearly shown the benefits of single membership for London's libraries. My goal is to ensure everyone can benefit from the richness they have to offer, and a single membership card will make it easier and quicker for people to benefit. I hope we can move to implement it quickly.' -- www.mla.gov.uk
