Save Room for the Back Matter

Most of you know I've been working on a picture book biography, and I'm finished with the story part and have been polishing up the back matter. Thank God for back matter! Do you know why? Well, I spent probably 
2 1/2 - 3 months of research on this person; my Evernote online notebook is full and so is my real hard copy notebook. But when I revised and revised this story, I had to cut out many facts and areas of this person's life. It was extremely painful. All those months of digging up these gems of facts and anecdotes, only to ditch them. But wait...those facts aren't gone forever. I can use them in my back matter or save them for a future web site spot for students and teachers. Relief!

So exactly what belongs in the back matter? I've been studying the pros, and the sky's the limit. Each book is unique in how its handled. Some leave a small author's note explaining how they were connected with the subject. Others leave 2-3-4 pages of additional information. Here are some examples:

In Noah Webster and His Words, the story stops on page 29. A double-spread timeline takes up pages 30-31, and on page 32 is more about Noah's life, and a bibliography divided into primary resources, secondary resources, and web sites.

In A Beam of Light, there are 14.5 spreads of story, then one double-spread with the author's note, four sections of additional information about Albert Einstein, and then books for further reading, plus one web site.

A Splash of Red includes 5 pages of back matter! The first page has a historical note (more info about Horace Pippin) plus his real photograph. The next spread includes the author's note, illustrator's note, a list of books for further reading, a film, web sites, quotation sources, and an acknowledgements section (thanking everyone who helped with the book including museum people). The last spread in the back matter is a map of places to find Horace's art. 

Who Says Women Can't Be Doctors has a double spread with the author's note of more about Elizabeth Blackwell and sources used.

Wow. The back matter is no simple matter! I think the more you have to offer the editor is better. And then the editor can choose what to use. I've already written a short author's note of how I'm connected with my subject, additional information about my subject (mostly those facts I had to cut out of the original story), a timeline, and a bibliography separated by primary and secondary sources. Perhaps I should slim the sources down for "further reading" for children. I also have a list of photographs in public domain that might be helpful to the future illustrator.  

I realized all this back matter must fit within the confines of a 32 page picture book unless the publisher decides on extra pages. Oh no! Perhaps more cutting. 

If you want to read more about back matter, I found a few posts.

What are your thoughts? What do you think should be included?
