Posted By Zyggy Turek Joe, we have been using TI via the internet for a couple of years now & taking everything into account, have been quite happy. The largest slice of the fee is for British Standards, & they used to quote a much smaller figure if you didn't want this facility. It all depends on how often you need to look a BS up, but then there is always your local library if this doen't happen very often. The data base of files is massive, but the downside of any IT system is if your local network fails, then so does the access. I know that Barbour have a similar system, but it is some time since I appraised it. Another plus with TI is that we also get to subscribe to other specialist sites which cover fire, construction, etc.
