Electronic resources are well-suited to satisfying some of the needs of open and distance learners: they are available at any time, and the library incurs no costs for storage, dispatch or circulation. This paper reports on a year of Demand Driven Acquisition (DDA) of EBL ebooks undertaken at the Open Polytechnic, comprising a six month trial from July to December 2009, and the first six months of DDA proper from January to June 2010. EBL's full catalogue of approximately 120,000 bibliographic records was loaded, and patrons were allowed to initiate their own requests for Short Term Loans. Autopurchases were set up to occur on the third loan request. Although DDA has received no promotion usage was steady from the start, with 1535 Short Term Loan requests and 83 Autopurchases fulfilled during the trial. Costs were monitored closely. The trial was judged to be a success, and the Open Polytechnic continued with Demand Driven Acquisition in 2010. From January to June 2010 steady usage continued, with 3003 STLs and 187 Autopurchases recorded over the whole year.
