English bibliography in Hebrew document (XeTeX)

Question

I am writing a Hebrew document all of whose bibliography entries are in English:

\documentclass{article}
\usepackage{polyglossia}
\setmainlanguage{hebrew}
\setotherlanguage{english}
\newfontfamily{\hebrewfont}{DavidLibre-Regular}
\newfontfamily{\englishfont}{Palatino Linotype}
\begin{document}
תרגום לאנגלית של אוקלידס נמצא ב-%
\textenglish{\cite{euclid}}.
\bibliographystyle{plain}
\bibliography{bib-test}
\end{document}

However, the bibliography is printed RTL: To change to LTR I added before the \bibliography command:

\selectlanguage{english}

This prints the bibliography correctly as LTR but also changes the title to LTR: I would like an LTR bibliography with an RTL title.

Answer 1

The bidi package provides the control sequence \setLTRbibitems precisely for this purpose. All you need to do is placing this control word before inserting your bibliography.

Answer 2

I still don't have an answer but I have a workaround. First change the class from article to book. Then add the following command to the preamble of the XeLaTeX source file:

\gappto\captionsenglish{\def\bibname{\raggedleft\texthebrew{ביבליאוגרפיה}}}

The result is what I want: A real answer would be appreciated.
