[unboggling]

I use this for sending to device: {author_sort:sublist(0,1,&)}

That lists the first or only author in author_sort whether there are more than one or not. The lastname is listed first in author_sort. For me distinguishing between one or two or three or too many (authors in author_sort) is too much trouble for not absolutely important information on the device. But I keep only a few books on device at a time.

For saving to disk, I use {authors} which I have as firstname lastname
