Book Sale at Neilson Hays Library this Weekend

Thousands of quality secondhand English language books at the book sale this weekend at Neilson Hays Library in Bangkok. Book sale is on 18-19 May 2013, from 9:30am-4pm. Prices start from only 50 Baht. The library is at 195 Surawong Road in Bangkok.
Is there a list of the titles that will go on sale this weekend?
I’ve never seen one.
Just saw this book sale from May 18-19…Is there any extension on this sale?
Sorry, not until next time.
I’ve been to one of their previous book sales and, indeed, they’ve got quality books at very decent prices!
