really answer the first part of the Noble Lord's question by saying that er er it is a question of future cost, er we are er we are already spending a great deal of money on the first part er of this er library and er we will have to examine the future cost very carefully and I put it to you to the Noble Lord that it would be a really sad reflection where the field of creative endeavour in which this country is m has most excelled over the centuries, in other words literature to have no single focus for celebration, preservation and active use, it really is er very important that this library continues, but may I remind Your Lordships also that we're not talking about the s the library in this question, we're talking about the u the site at present used by the builders.
