Unable to Call "Publisher" or "Location" in Biblatex

Question

I am trying to add the final touches to a customisation of Biblatex. However, for book I am unable to call publisher or location. I am using

\DeclareBibliographyDriver{book}{%
    \printnames{author}%
\   \newblock
    \printtext[parens]{\printfield{year}}\addperiod%
\   \newblock
    \printfield{title}%
\   \newblock
    \printfield{edition}%
    \newunit\newblock
    \printfield{publisher}%
    \newunit\newblock
    \printfield{location}%
}

with the bibtem

@book{B:random-graphs,
    location = {{Cambridge}},
    title = {Random {{Graphs}}},
    edition = {2},
    series = {Cambridge Studies in Advanced Mathematics},
    publisher = {{Cambridge University Press}},
    date = {2001},
    author = {Bollob{\'a}s, B{\'e}la},
    doi = {10.1017/CBO9780511814068}
}

This outputs the following.

I don't understand why the \printfield{publisher} and \printfield{location} lines don't make this as follows:

B. Bollobas (2001). Random Graphs 2nd ed. Cambridge University Press Cambridge

Assistance would be most appreciated! :)

Answer 1

biblatex 'fields' come in three major flavours

1. field printed with \printfield
2. list printed with \printlist
3. name list printed with \printnames

So you need to know the type of the 'field' you want to print and choose the correct \print... command.

You can find out about the type of each 'field' in the biblatex documentation, §2.2 Entry Fields.

Both publisher and location are actually lists, so you need

\printlist{publisher}

and

\printlist{location}
