What does this reference mean?

Question

I saw this in this fatwa, 

al-Silsilah al-Da’eefah (1/270-274) 

What does this mean, if it indicates any page of a book, can you please post it?

Answer 1

It is a work by Nasiruddin al-Albani, the numbers in the brackets with a slash usually mean a volume and page numbers. Here is a scanned copy.
