Hardcopy (paperback) versions for volume 1 and volume 2 of Symbolic Logic are now available! This most recent version of the text includes many improvements relative to previous versions.

*Amazon will raise prices for print on demand books starting June 20, 2023. Currently Symbolic Logic goes for about $10.00/volume. The cost will go up to around $14.00. This is disappointing to me insofar as I have been working with the lower price in mind. Still, either way, it remains a good deal. And the lower price is available at least for this next week.
