I always have problems with prepositions and pronouns in subordinate clauses. For instance, if I have the following sentence: "I'm looking for a book and I know its ISBN." I would like to use a subordinate clause instead but everything I come up with doesn't sound very idiomatic, e.g.: "I'm looking for a book of which I know the ISBN." What would be the best way to say it, if any?

Welcome, Sir W.
"I'm looking for a book of which I know the ISBN" is just fine, though rather formal.
You could also say "I'm looking for a book whose ISBN I know". The pronoun 'whose' is not used exclusively for people.
