Always in search of books to buy in the Latin language, I have finally come across a very efficient resource.
bookdepository.com (with Latin filter on)
Free worldwide shipping too!
Just click Latin in the Advanced search, Language box. Tens of thousands of titles available! An extraordinary and unique resource. (Just click above, the image or their web address, and you will be on your way). No need to buy the expensive and somewhat bland Loeb classics anymore! So many options on so many classical works in the original and/or with translations to your preferred language!
There is also an Ancient Greek language filter! Wunderbar!
If I buy Latin or Greek books with translation, I usually like to get them in a language which is not English, e.g. German, so as to improve my modern foreign languages along the way! That also forces you to pay closer attention to the Latin than in the Loeb dummy editions with English on the facing page!
Neither Abebooks, Bookfinder or Amazon have this easy Latin language filter. My library just acquired dozens of new titles in lingua latina! Deo gratias! Enjoy!
P.S. I am happy that these booksellers are out competing Amazon, which I somewhat detest for it's unfair monopolizing strategies.
In any case, the other book search engines should upgrade to include this Latin language filter.
And while they are at it, they should add a parallel Greek function with the Greek classics, more difficult because of the modern Greek literature.
