Here is the PDF version.

This is a bit of an odd one: my colleagues built a Google Slides presentation, I used L^AT_EX, and then I used a tool to glue together, in the proper order, the PDF pages saved out of Google Slides and mine.

However, for remixing purposes, you can copy and adapt pages from those two sources as you like.

Here are the files:

1. The Google Slides part, in three different [presumably equivalent?] formats:
   1. GSpart.odp
   2. GSpart.pdf
   3. GSpart.pptx
2. The two L^AT_EX parts I did:
   1. first.tex
   2. second.tex
3. Required image files (mostly needed for the L^AT_EX part):
   1. all_CC.pdf
   2. CC-BY.jpg [for importing into the Google Slides part]
   3. CC-BY.pdf
   4. commercial_highlighted.pdf
   5. costs_graph.pdf
   6. costs_key.pdf
   7. ldlos_cover.pdf
   8. openstax_chemistry.pdf
   9. textbooks1980.pdf
   10. textbook_pain.pdf
   11. yaintt_cover.pdf

On my machine, which is running Linux Mint "18.3 (Sylvia)" and which has a quite complete suite of texlive packages (including, crucially, texlive-base and texlive-latex-base; other required L^AT_EX packages will be obvious to anyone who knows L^AT_EX when looking at the \includepackage commands in the first.tex and second.tex source files), at the command line, I used pdflatex, pdfseparate, and pdfjoin to build the final, complete PDF slide deck for the presentation. Come to think of it, I also had to open some of the files in xpdf and print them "to a PDF file" choosing a specific page size so that when I pdfjoined them, they all looked good together. Your mileage may vary, of course.

If you want just to download one archive with all of those files in it, you could use either of the following two choices:

• OERatACAOFiles.tar — a tar archive, for Linux users
• OERatACAOFiles.zip — a zip archive, for users of other operating systems
