@maxdancona,
I collect these early school science books (mostly biology and agricultureal botany). They are so "of the time" and they are preachy about "inferior races", and Bibical Creationism. Ive looked for them on line to lift sections for discussion in classes (in one case I used em in a court case). I was disappointed at what is not preserved on line, so keeping these books is vital to make arguments about how , less than fact based, was our earlier education process.
Fortunately the cell phone is probably the easiest way to make"clips " of segments of these books for student notes and court documents
