What does "Hardback: 0-521-85313-1:208pp" mean?

Question

I read an advertisement and it says at the end of it "$72:Hardback: 0-521-85313-1:208pp". But I can't figure out the meaning of "0-521-85313-1:208pp. Can anybody shed some light on this for me.

Thanks,

Answer 1

looks like the ISBN of a book and the 208pp are the page numbers

my database pulled up Weeds in the Garden of Words: Further Observations On The Tangled History Of English Language

sound familiar?

Answer 2

That is your ISBN number. It tells you how to find the book and that this particular version is the hardbound (as opposed to the paperback). Oh, and it's 208 pages long
