Texmaker bibliography issues (no article helped so far...)

Question

I am currently preparing my research proposals. I have three general topics left. Before focusing on only one, I would like to hand in a single document with all three research proposals on (and three bibliographies) with the following structure:

Topic 1

1. Idea and hypothesis -> text
2. Literature -> bibliography (using \nocite(*))
3. Methodology -> text

Topic 2

1. Idea and hypothesis -> text (some \cite(...))
2. Literature -> bibliography (using \nocite(*))
3. Methodology -> text

Topic 3

1. Idea and hypothesis -> text (some \cite(...))
2. Literature -> bibliography (using \nocite(*))
3. Methodology -> text

I am using TexMaker and JabRef. I also tried all given possibilities of using either, some or all used packages under %Bibliography. Below my code:

\documentclass[10pt,a4paper]{article}

%Layout

\setlength{\parskip}{1em}

\addtolength{\textwidth}{1.75in}
\addtolength{\topmargin}{-.875in}
\addtolength{\textheight}{1.75in}

The issue is, even though the bib files are in the same folder and I ran the usual quick build (1x pdflatex, 1x bibtex, 2x pdflatex) the bibliography doesn't show up and the citations made in the text are shown as [?].

Where is the mistake in the code? In my TexMaker code \bibliography{...} stays blue and doesn't turn to the usual code colors of grey/red. I am eternally grateful for you help.

Answer 1

I suggest you use biblatex, which is easier to customise, has an apa style. Preferably compile with biber.

\documentclass[10pt,a4paper]{article}
\usepackage[utf8]{inputenc}

Answer 2

Expanding on my earlier comment, you can use the multibbl package:

\documentclass[10pt,a4paper]{article}
%Layout
\setlength{\parindent}{2em}
\setlength{\parskip}{1em}
\renewcommand{\baselinestretch}{1.5}
\addtolength{\oddsidemargin}{-.875in}
\addtolength{\evensidemargin}{-.875in}
\addtolength{\textwidth}{1.75in}
\addtolength{\topmargin}{-.875in}
\addtolength{\textheight}{1.75in}

However, for this to work I had to remove the cite and cleveref packages, because multibbl redefines commands like \cite to take two arguments: the first of these is the bibliography you want to cite from.

To compile the above, after running latex (or pdflatex) as usual, you need to do bibtex divestitures, bibtex debtrenegotiation and bibtex hedgefunds to run bibtex on all three bibliographies. You then need to run latex (or pdflatex) twice more. Some TeX editors will have build sequences that know to run bibtex on these different aux files, while for others you may just have to do it from a command prompt.
