The data in the Register is compiled and revised at least annually.
The Register provides details about publishers but it does not include information about specific publications. However, if you already know the SNBVE of the book, you can use the Register to find out how to contact the publisher for more information.
Simple search facilities are available to all – successful results will display the publisher name and SNBVE prefix (or full SNBVE in the case of small publishers) automatically.
