I don't know when or where I bought my copy, but what's odd/interesting is that there is no date anywhere that I could find. Printing date, copyright.. nothing.
It's the simple meaning. Timeless!
I wish more books were made with these thick, vinyl/flexi/plastic covers. I've got some other [mini] L dictionaries that are dated from the mid-80s. Indestructible.
I checked the listings on Amazon--some editions may go back as far as 1912 but none of the covers exactly matches my copy's cover. I would guess post-1945 because it says Printed in Germany and there probably wasn't much of a market for Hebrew-English dictionaries in Germany between 1933 and 1945.
