I would like to use multiple bib-files for multiple bibliographies in my seminar work (I want to split books from internet sources). To simplify it, I tried to create 2 bib-files and then do
\section{Books}.
\bibliography{sourcesbooks}
\section{Internet sources}
\bibliography{sources2}
But this just prints the same bibliography 2 times. I also tried some packages, like multibib, bibtopic, etc. (I am using jurabib for footcites and so on).

This is now implemented in Biber 0.9.8. Here is how to deal with your question. Given the sample file:
\begin{filecontents}{\jobname-primary.bib}
@BOOK{hectic,
AUTHOR = {Henry Hectic},
TITLE = {How Horticulturalists Howl},
PUBLISHER = {Honorary Books: Henage},
YEAR = {2000}
}
\end{filecontents}
\begin{filecontents}{\jobname-secondary.bib}
@BOOK{flutter,
AUTHOR = {Frederick Flutter},
TITLE = {Fraternising with Flowers},
PUBLISHER = {Frippery Pamphlets: Folkestone},
YEAR = {1995}
}
\end{filecontents}
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[backend=biber,style=authoryear]{biblatex}
\usepackage{csquotes}
\addbibresource{\jobname-primary.bib}
\addbibresource{\jobname-secondary.bib}
\begin{document}
Some citations: \cite{hectic}, \cite{flutter}.
\printbibliography[title=Primary Sources, keyword=primary]
\printbibliography[title=Secondary Sources, keyword=secondary]
\end{document}
You can automatically add the correct keywords to your data as Biber reads it by using the following biber.conf file:
<?xml version="1.0" encoding="UTF-8"?>
<config>
<sourcemap>
<maps datatype="bibtex" bmap_overwrite="1">
<map>
<per_datasource>test-primary.bib</per_datasource>
<map_step map_field_set="KEYWORDS" map_field_value="primary"/>
</map>
<map>
<per_datasource>test-secondary.bib</per_datasource>
<map_step map_field_set="KEYWORDS" map_field_value="secondary"/>
</map>
</maps>
</sourcemap>
</config>
This will add the necessary keywords based on the datasource names. If you already had a KEYWORD field in your datasources which you wanted to keep, you could use the match/replace functionality instead:
<?xml version="1.0" encoding="UTF-8"?>
<config>
<sourcemap>
<maps datatype="bibtex" map_overwrite="1">
<map>
<per_datasource>test-primary.bib</per_datasource>
<map_step map_field_source="KEYWORDS" map_match="^" map_replace="primary,"/>
</map>
<map>
<per_datasource>test-secondary.bib</per_datasource>
<map_step map_field_source="KEYWORDS" map_match="^" map_replace="secondary,"/>
</map>
</maps>
</sourcemap>
</config>
The Biber manual has been updated in 0.9.8 with documentation of the
config file format and has more examples. The format of the user
config file is a major change from 0.9.6 (and some changes also from 0.9.7) as the older format was a bit
of a mess and couldn't be extended to cope with situations like this
due to inherent limitations of the format itself. I opted for a real
XML format for flexibility. You can also validate your config file now
by passing the --validate_config option to Biber.
EDIT: Since biber 1.3, you there is an "append" mode for setting values in sourcemaps so it's easier like this, which deals with entries with or without an existing KEYWORDS field when you want to keep any existing values:
<?xml version="1.0" encoding="UTF-8"?>
<config>
<sourcemap>
<maps datatype="bibtex" bmap_overwrite="1">
<map>
<per_datasource>test-primary.bib</per_datasource>
<map_step map_field_set="KEYWORDS" map_field_value="primary" map_append="1"/>
</map>
<map>
<per_datasource>test-secondary.bib</per_datasource>
<map_step map_field_set="KEYWORDS" map_field_value="secondary" map_append="1"/>
</map>
</maps>
</sourcemap>
</config>
Here is the same thing using the biblatex macro interface which you can put directly in your document:
\DeclareSourcemap{
\maps[datatype=bibtex, overwrite]{
\map{
\perdatasource{test-primary.bib}
\step[fieldset=KEYWORDS, fieldvalue=primary, append]
}
\map{
\perdatasource{test-secondary.bib}
\step[fieldset=KEYWORDS, fieldvalue=secondary, append]
}
}
}
Here's a biblatex solution that satisfies your main requirement -- a combination of local bibliographies and a global one, with congruent local/global entry labels. However, instead of individual .bib files for each section I use a global file including special keywords fields to indicate an entry's affiliation with one or several sections.
\documentclass{article}
\usepackage[style=alphabetic]{biblatex}
\defbibheading{subbibforsec}[\refname\ for section~\thesection]{%
\subsection*{#1}}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@misc{A01,
keywords = {foo,bar},
author = {Author, A.},
year = {2001},
title = {Alpha},
}
@misc{B02x,
keywords = {foo},
author = {Buthor, B.},
year = {2002},
title = {Bravo},
}
@misc{B02y,
keywords = {bar},
author = {Buthor, B.},
year = {2002},
title = {Bravissimo},
}
\end{filecontents}
\addbibresource{\jobname.bib}
\nocite{*}
\begin{document}
\section{Foo}
Some text \autocite{B02x}.
\printbibliography[heading=subbibforsec,keyword=foo]
\section{Bar}
Some text \autocite{B02y}.
\printbibliography[heading=subbibforsec,keyword=bar]
\printbibliography
\end{document}

Please in the future post a compilable minimal example from which to start helping you to get what you want.
However, as samcarter already said: It will be a very good idea for you to switch to BibLaTeX, where all of this will be very easy. There, you can add as many bib-files as you want, using several
\addbibresource{}commands. You can then simply print separate bibliographies per entry-type usingOr you can apply even finer separation of entry-types, by first defining separate bibfilters and using the subtype-field per entry, eg.
