Welcome to issue 4 of BDSlife Online, your regular features, news and views from BDS. In this issue we visit Vienna and the Austrian National Library where we look at the history of a great library catalogue and Baroque library. We also report on the return of the London Book Fair to Olympia and preview forthcoming events and conferences where BDS will be presenting its Academic Library Licence. We pay tribute to the life of David Lindley and our Chief Metadata Officer, Jenny Wright, loves metadata in an article published in Catalogue and Index and new markets and areas for growth are explored, notably with Newbooks Solutions and the ISNI standard. Ten years of working with Oxford University Press is celebrated and BDS's alliance with Absolute Classics announces the arrival of Mozart's Marriage of Figaro in Dumfries this summer.
