CILIP recently revamped Lisjobnet, its job advertisement site. You can now search by keyword, location, or secor, which is welcome if overdue.
It would be nice to have definitions of their geographical areas. I live in Bedfordshire, for which it is always hard determine the correct region. I think I would come under East of England. Something few job search sites do is let you combine areas: I would like to look at Hertfordshire (South East), Bedfordshire, and Cambridgeshire without checking two times or more times. There are other related problems, such as not being able to combine sector and location.
Most importantly, there is no RSS feed, although it wouldn’t be much use if you couldn’t refine a little more than All Jobs. There is at least an email alert now, but that does just give you All Jobs.
