[Koha] Report help

[Katharina Penner]

Dear all,

I need to create a report to extract all metadata on all authors. I want to
have each aspect - surname, name (or initials), dates, expansion of
initials, other possible fields - appear in a separate field/column, in a
delimited way. We're using UniMarc so these would be fields 700 a, b, c, f,
g, $4. So far the data come up all in the same field.

Please help!
