'biographie' is a book about someone's life (you find many of these for celebrities and historical characters); 'une bibliographie' is the list of reference books at the end of a particular book, like all the other books you had to research to write that one, or the ones that could be useful for the readers who want additional information.
So at the end of the 'biographie' (English: biography), you will often find the 'bibliographie' (English: bibliography).
"Biographie" refers to a written account of someone's life, while "Bibliographie" refers to a list of sources or references used in a scholarly work. Both terms are related to information about individuals or works, but in different contexts.
