Thanks Sue. Now found the page in the August issue. As David has no computer I'll have to write to him. I want to make sure the CD for Arbory will be the 1729-1988 range as in the book & that Rushen will be the 1712-1968 . As both these books together would cost £26.50 plus p&p it would be better to buy the one CD at £12.50. The problem with Cds is they can be useless on some computers. (We have about 50 CDs that we cannot use on 2 of our computers ! )
