As well as publishing the Bibliography of Welsh Periodicals 1851-1900 in 2000, the National Library of Wales also intends to publish a Supplement to Libri Walliae, compiled by Charles Parry. lt will contain some 900 items not included in the original work published in 1987, some of which are additions, others corrections. The National Library of Wales is currently installing a new computer system for its collections ofprinted materials. The system will offer a new facility, namely the opportunity to scan certain sets of data from the total database resource, notably to Welsh books 1546-1820, books of Welsh interest from the nineteenth century and books ofWelsh interest from the twentieth century. It is expected that the system will be operational by the beginning ofthe year 2000. Cyswììt/Contact: Dr Rhidian Griffiths (wrg@llgc.org.uk)
