[Koha] Content on labels

[Steven Nickerson]

Hi all,

   We are running the package version of 3.16.02 and I'm wondering if on a
small "spine" label I can limit the number of characters printed?
Currently we include the entire "author" field but we'd like to  limit that
to only the first 8 characters of the "author"?   When defining a Label
Layout can I simply check the "List Fields" radio button and then use
standard SQL like 'LEFT(author,8)'?  If not, anyone know of another way to
limit it?

 

Thanks!

Steve
