I am studying open university K269 social work, social care and the law and this book has some useful and easy to access information. It gives clear details of legislation and information on books and other sources of information. I would think it is even more useful for pracicing social workers.
While it gives some overview over some things, unfortunately the law changes constantly and as such it is rather often outdated. In many parts, instead of having actual information and content, the other just tells you which other books you should read. Wouldn't recommend it to be honest.
