[Tex/LaTex] How to change Natbib style to a custom format/Bibtex

Question

Part 1 of the problem:

I need the bibliography to cite like:

LastName, First letter of first name (year of publication). Title. Place: publisher

the closest i got was using the humannat style but that isn't good enough.

Part 2 of the Problem:
I also do not know how to accomplish complex Citations like from anthologies. I need to do it like:

Ulm V. Title of text. In Füchter A., Moegling K. (Hrsg.), Title of Anthology. Place: publisher. Sites of the text.

I really have no clue how to achieve something like that. Normally i write anything i latex but without your help i am afraid that i would have to use word…

Answer 1

With biblatex many small modifications to styles are fairly straightforward. Guidelines for customizing biblatex styles gives a short overview over the most common changes.

The standard styles print the name of editors after the booktitle for @inbook and @incollection, so I based the answer on my style bundle biblatex-ext, where you can easily move the name with the option innamebeforetitle=true.

\documentclass[british]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=ext-authoryear, backend=biber,
           giveninits=true, uniquename=init,
           innamebeforetitle=true]{biblatex}


\DeclareNameAlias{sortname}{family-given}
\DeclareNameAlias{ineditor}{sortname}

\DeclareDelimAlias{finalnamedelim}{multinamedelim}

\DeclareFieldFormat{editortype}{\mkbibparens{#1}}
\DeclareDelimFormat{editortypedelim}{\addspace}

\DeclareFieldAlias{translatortype}{editortype}
\DeclareDelimAlias{translatortypedelim}{editortypedelim}

\DeclareDelimFormat[bib]{innametitledelim}{\addcomma\space}

\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{sigfridsson,gaonkar:in,westfahl:space}
\printbibliography
\end{document}
