Changing the dashed option
We can achieve this by calling \AtNextBibliography{\renewbibmacro*{bbx:savehash}{}}, which redefines bbx:savehash bibmacro (the one that tells the style to save and use dashes) at the beginning of the next \printbibliography (it can be used out of the preamble).
\AtNextBibliography{\renewbibmacro*{bbx:savehash}{}}
Removing the alphabetical label in the date
It's the same principle of changing the dashed option: we must set the blx@labeldate toggle to false within a given bibliography; once again, we use \AtNextBibliography to set it, and we will use it within a refsection.
\AtNextBibliography{\settoggle{blx@labeldate}{false}}
Here's a MWE:
(\DeclareSourcemap is used here to easily produce a list of a single author's publications. For more details, refer to How to print a bibliography for a particular author only?)
\documentclass{article}
\usepackage[style=authoryear]{biblatex}
\addbibresource{biblatex-examples.bib}
\DeclareSourcemap{
\maps[datatype=bibtex]{
\map{
\step[fieldsource=author,
match=Kant,
final]
\step[fieldset=keywords, fieldvalue=own]
}
}
}
\begin{document}
\autocites{knuth:ct,knuth:ct:a,companion,kant:kpv,kant:ku}
\begin{refsection}
\AtNextBibliography{
\renewbibmacro*{bbx:savehash}{}
\settoggle{blx@labeldate}{false}
}
\nocite{*}
\printbibliography[keyword=own,title={These are my Works}]
\end{refsection}
\printbibliography[title={These are awesome works by other people I like}]
\end{document}

\regexp{}since it has no tricky regexp characters in it,match=Kantworks fine. – PLK Aug 10 '13 at 09:24labeldaterequirement. I also expanded the example and the text to try to address some of the issues form your first comment. – henrique Aug 10 '13 at 17:03\AtNextBibliography{\renewbibmacro*{bbx:savehash}{}}. (Had to figure out first, though, that this is only available since April 2013 or so, and MikTeX hasn't packaged that one yet, so I had to install manually). I was unable to use keywords to distinguish my publications from others because I'm already using it to distinguish different types of publications, i.e. I'm printing several (sub-)bibliographies within that refsection. So all I had to do is insert the '\AtNextBib...'-thing before everty\printbibliography. – Christoph Aug 11 '13 at 21:26
