I just read Lauren Redniss's "biography" of Doris Eaton Travis, Century Girl. (For you Goodreads habitues,
http://www.goodreads.com/book/show/158570.Century_Girl" target="_blank) The quoted word is not a critique but rather a comment on the format of the book, which is written more in the style of a graphic novel or large format art book rather than a standard biography, physically mimicking a scrapbook. Redniss interviewed Doris and was given access to the Eaton family papers and scrapbooks (Doris's mother kept scrapbooks for all her children). Your mileage will definitely vary on whether you find this format enchanting or irritating. I"m a word-oriented reader so it rapidly wore out its welcome for me and I found the text (done in faux-handwriting) difficult to read. Nevertheless the photos and articles Redniss uses throughout the book are fabulous.
The book is not particularly detailed and close examination is not one of its strengths (I polished it off in about an hour and a half), but Doris herself comes out looking like what she probably was, a tough lady who rolled with the punches. She never stopped dancing throughout her life, for her dancing was a joy instead of just a job, which is probably why she lived so long. I would like to have seen more attention paid to her family life and her non-relationships with her father and elder brother. But that's just me.
So I'm firmly, uncategorically stating that recommendation-wise, you're on your own with Century Girl.
