Thanks Kirsten, Vijaya, and Betsy.
I think I’m having a hard time culling, and also I’m just looking for interesting ways to shape the pile of information I’m working with. But I agree, Betsy—it is, overall, an enjoyable process!
In this particular case, I will have a diagram, a simple timeline, plus about 800 words of additional information about my subject. Bibliography and websites will be on a separate page, so I don’t have to worry about fitting that in.
Part of my concern is that the back matter will be considerably longer than the main text (which is quite brief). Some people have suggested that that can be problematic. I don’t want to load the main text any further, but I could consider keeping the back matter more in line with it.
In part I was wondering if people have noticed things that are effective but not necessarily typical. Or if teachers and librarians have things they wish authors would do, or find particularly useful. For example, I have seen several books that include keywords to search, rather than actual websites. Seems like that gives you less control over where you direct the reader, but it might avoids those annoying broken links. Anyway, I thought it was an interesting idea.
