Hi, I recently posted a message regarding libraries changing over from hard copy reference materials to on-line Internet based ones. Thanks to everyone who responded - I now have another query has anyone encountered problems with Internet based reference materials and the use of IP addresses through the firewalls. At Walsall we are looking at some packages but have had problems regarding individual IP addresses on our public access machines - has anyone else experienced these type of problems ? Any replies gratefully accepted!
