Campos obrigatórios do Bibtex para livro e artigo

Question

Como você não nos forneceu nenhum código tex para construir a bibliografia, acabei de usar meu arquivo de teste bibtex padrão para sua bibliografia.

O motivo dos seus erros são algumas vírgulas faltando no final de algumas linhas do seu arquivo bib.

Por favor, veja o seguinte código

\usepackage{hyperref}   % better urls


\begin{document}

This is text with \cite{Goossens} and \cite{adams}.

\nocite{*} % to test all bib entrys
\bibliographystyle{unsrt} % <===========================================
\bibliography{mybibfile}

\end{document}

e seu resultado após compilar sem erros e com um aviso (falta o título do livro, o que é certo!):

Se possível altere a redação dos autores parafamilyname, name and familyname2, name2 name2 and familyname3, n3.

BTW: usei o pacote filecontentsaqui apenas para corrigir o arquivo bib e o código tex concatenados a um MWE de compilação. Você não precisa usar package filecontents!
