Even when my .bib file has uppercase words, I can not preserve them when generating de bibliography page.
For example:
\documentclass{book}
\usepackage{csquotes}
\usepackage[style=apa, backend=biber]{biblatex}
\DeclareLanguageMapping{english}{english-apa}
\bibliography{mybib}
\begin{document}
This is a sample text of \textcite{Book1} and \parencite{Book2}
\printbibliography
\end{document}
with this mybib.bib file:
@book{Book1,
author = {First, Author},
title = {The First Title. Four uppercase words},
year = {1234}}
@book{Book2,
author = {Second, Author},
title = {This title is AWESOME},
year = {2050}}
generates this bibliography:

How can I preserve my uppercase words?
title={{The First} {Title}. {Four} uppercase words}should do the trick. – Johannes_B Feb 04 '15 at 22:10biblatexwith Biber, it's not a duplicate as marked. – egreg Feb 04 '15 at 22:50
