I hadn’t noticed until today, but among the volumes available at Loebolus is Aristotle’s Rhetoric (vol. 193; ed. J. H. Freese, 1926).
A new collection of online Loeb Classical Library volumes is now available (HT: Charles Jones). This new collection provides locally-hosted PDFs that can be downloaded without completing a CAPTCHA field. The page also provides a link to a single ZIP file (3.2 GB) that contains all the individual LCL volume PDFs available on the page.
