Salvete omnes!
I have come upon Linney’s Latin Class on the net and would like to follow along for review. I’ve downloaded the audio files.
However, is the book he’s using, “The First Year of Latin” by Walter B. Gunnison in the public domain. The book came out in 1917.
Where could I find a pdf of this one?
Gratias vobis ago et valete!
An old edition can be found in its entirety on Google Books here. A newer edition also shows up in the search results but can’t be browsed.
Or try:
http://www.archive.org/search.php?query=Gunnison%20Latin%20AND%20mediatype%3Atexts
Click on the title, then on All files:HTTP, then right-click on the pdf file and SaveTarget As…
Cheers,

Gratias vobis ago, amici! 
Valete!
Q-ut-D:
You mention in your first post:
The book came out in 1917
But that was the 1917 edition. Linney is using the 1902 edition, which is different. The download you need is Imber Ranae’s Google version OR the THIRD download version listed in Internet Archive.
