So, after all the housecleaning today, there are also labels that pull up display pages for the modules, showing the index page for every unit in that module. For example, here are the Native American units. Those labels should be really handy as students are deciding which unit they want to read in any given week. I haven't figured out yet just how to organize the index pages for each unit; that is the next housecleaning task I need to work on.
I've also created labels to organize the books into groups, and I've begun the process of standardizing my book pages, deciding on which web sources to cite for the online books. So, here are some examples of posts that I've revised to reflect the kinds of online sources I think are worth listing; I'm using the label "donelib" just to keep track for myself of which posts have good bibliographies: finished book posts.
Meanwhile, you can see the various book labels here, like the Native American Books, for example, or the Free Audio Books.
