The file format extension of
.bib stands for the "bibliography"; a file that the BibTeX engine gets as an input. The file-format-extension of
.bst has been derived from the expression of "bibliography style", as an equivalent command in LaTeX represents the same.
But, what does the
.bbl file-extension stand for in LaTeX? Is it derived from, or has something to do with the "bibliography library" or perhaps "bibliography for LaTeX", or even "bibliography lists"?!
I appreciate response, specially the ones with references.
