# Bibliography backref on new line with smaller font size

At the moment I use

\usepackage[style=authoryear,dashed=false,
abbreviate=false,
natbib=true,backref=true,backend=biber]{biblatex}
\setlength\bibitemsep{1.7\itemsep}
\bibhang=0pt % don't ask, I'm still experimenting ;)


which outputs entries like

Eddy, Sean R (Nov. 2004). "How do RNA folding algorithms work?" In: Nature
Biotechnology 22.11, pages 1457–1458. ISSN: 1087-0156 (cited on page 1 and 3).


But ideally I'd like to have it like

Eddy, Sean R (Nov. 2004). "How do RNA folding algorithms work?" In: Nature
Biotechnology 22.11, pages 1457–1458. ISSN: 1087-0156.
(Cited on pages 1 and 3.)


with the backref line in a smaller font size. Note also the big "C" in "Cited" and the different punctuation.

Background info: I think the backref shouldn't be part of the actual main bib information as it's not an info from the article/book/whatever. Of course, the same is true for the "visited on" part but these kind of references (websites) are the exception anyway.

\documentclass{article}

\usepackage[style=authoryear,backref=true]{biblatex}

\setlength\bibitemsep{1.7\itemsep}

\renewcommand*{\finentrypunct}{}

\renewbibmacro*{pageref}{%
\iflistundef{pageref}
{}
%    {\printtext[parens]{% DELETED
{\newline\footnotesize\printtext[parens]{% NEW
\ifnumgreater{\value{pageref}}{1}
{\bibstring{backrefpages}\ppspace}
{\bibstring{backrefpage}\ppspace}%
%      \printlist[pageref][-\value{listtotal}]{pageref}}}}% DELETED

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
author = {Author, A.},
year = {2001},
title = {Alpha},
}
@misc{B02,
author = {Buthor, B.},
year = {2002},
title = {Beta},
}
\end{filecontents}


This is a wonderful solution and exactly what I was looking for. - But it behaves a little bit faulty, at least if being used with biblatex-apa style. \addperiod always adds a period - even after additional remarks in parentheses and after URLs where no periods are supposed to be. If I comment out this line the final period vanishes but also from any other bibliography entry where it is needed. How to resolve this? – Psychic Birdy Oct 22 '12 at 20:26
