Great shakes for published authors

The IPKat has received an email from Shaker Publishing which reads, in relevant part, as follows:
"Dear Author,
If you published an academic or scientific text in 2006 that was also distributed in Germany you can register this with Verwertungsgesellschaft WORT (royalties collecting society) before 31 January and thus ensure an additional income on your copyrights. Apart from proceeds from sales of actual books, this means you can also profit financially from the secondary use of your works".
