Pulling Information out of Bibfile

Question

I would like to organize the papers I've read in the way outlined here https://academia.stackexchange.com/questions/10578/how-to-read-and-take-notes-on-research-papers/10616#10616.

But it kind of annoys me to write out author and year and things like that, which are already in my global bib-file (or should be). Also, I would like mistakes corrected everywhere if I correct them in the bib-file. Is there a way to get at the information from the bib-file for my latex-document?

So, instead of: (shamelessly copied from above post)

\section{Paper #1 Name, Authors, Date, \cite{...}}
My summary of the motivation and findings of the paper, or whatever I find interesting.
May be as short as a few sentences or as long as a page, depending on how relevant it is. 
\index{an important word}

I would want to write something like:

\section{\mycitetitle{citekeyfrombibfile}}
\citeurl{citekeyfrombibfile}
notes and so on

where \mycitetitle would expand to Title, Authors, Year and \citeurl would expand to the url (if available). I guess this would be a case for biblatex, but I am just starting with that and not yet sure what it can do.

Answer 1

Here is a solution using biblatex

\documentclass{article}
\usepackage[hyperref]{biblatex}
\usepackage{hyperref}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@book{Goossens1994LaTeX,
  author = {Michel Goossens and Frank Mittelbach and Alexander Samarin},
  title = {The \LaTeX{} Companion, $2^{nd}$ Edition},
  publisher = {Addison-Wesley},
  year = {1994},
  url = {www.tex.stackexchange.com}
}
\end{filecontents*}

\DeclareCiteCommand{\citepaper}[\section]
  {}
  {\bibyhyperref{Paper 
     \printfield{title}, 
     \printnames{author}, 
     \printfield{year} 
     \mkbibbrackets{\printfield{labelnumber}}}}
  {}
  {}
\addbibresource{\jobname.bib}

\begin{document}

\citepaper{Goossens1994LaTeX}

\end{document}

The solution implements a new cite command (\citepaper) printing the desired/required information.

Answer 2

Why not bibentry?

\documentclass{article}
\usepackage{filecontents}
\begin{filecontents*}{mybib1.bib}
@book{Goossens1994LaTeX,
  author = {Michel Goossens and Frank Mittelbach and Alexander Samarin},
  title = {The \LaTeX{} Companion, $2^{nd}$ Edition},
  publisher = {Addison-Wesley},
  year = {1994{.}},
  url = {www.tex.stackexchange.com}
}
\end{filecontents*}
\usepackage{natbib}
\usepackage{bibentry}
\begin{document}
\bibliographystyle{unsrtnat}
\nobibliography{mybib1}

\subsection*{\bibentry{Goossens1994LaTeX}}

\end{document}

Answer 3

Just for the sake of completeness, an alternative method I have found while waiting for answers is:

\documentclass{article}
\usepackage[hyperref]{biblatex}
\usepackage{hyperref}
\usepackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@book{Goossens1994LaTeX,
 author = {Michel Goossens and Frank Mittelbach and Alexander Samarin},
 title = {The \LaTeX{} Companion, $2^{nd}$ Edition},
 publisher = {Addison-Wesley},
 year = {1994},
 url = {www.tex.stackexchange.com}
}
\end{filecontents*}
\addbibresource{\jobname.bib}

\newcommand{\mytitlecite}[1]
 {\texorpdfstring{\citetitle{#1}, \citeauthor{#1}, \citeyear{#1},\cite{#1}}{#1}}
\begin{document}

\section{\href{file.pdf}{Paper} \mytitlecite{Goossens1994LaTeX}}

\end{document}

Where file.pdf is the file containing the paper on the local file system. This also avoids warnings from hyperref. The other answer could be extended to do that however, and has the extra feature that the whole section title is clickable, not just the label.
