Any experience with Authors' Licensing and Collecting Society?

In our March "how can we help you?" thread, a reader asks:

Has anyone had any experience with the Authors' Licensing and Collecting Society (ALCS) in the UK? They say they can collect royalties for published articles. This seems too good to be true. Are academics actually able to make money this way? If so, how much and is it worth it?

I've never heard of this, but maybe it's because I'm not in the UK? 

Do any readers have any tips or other insights to share?

My colleague in a UK department says it's legit, for things published with a publisher registered in the UK. "I get 200-300 pounds a year, on the basis of a few book reviews and a couple of chapters in collections."

As the first person says, it is legitimate and you can get a small amount of money each year. I don't seem to get quite as much as the reported amount in the comment, and I've published several books and quite a few journal articles, but it's still nice to get a couple of hundred pounds a year. Maybe I'm doing something wrong and can get more. Either way, it definitely seems worth doing.
