Please explain me the difference in usage of "that contains" and "containing" in the below two sentences.

Perhaps every travel guide that contains references to Italy recommends that tourists, especially those in search of a romantic atmosphere, visit the uniquely beautiful, "floating" city of Venice.

Is there any difference between the meaning of the above two sentences ?
In the situation like above, please guide me which sentence should I choose. One is using "that contains" and other using "containing". On which situation(s) do we use "that contains" and "containing".

Let me give it a try. Instructors please correct me.

Basically, we are discussing that contains vs containing

here the part - [that contains]/[containing] references to Italy - is very important to the meaning of the setence becuase Venice is in Italy. Only if there is reference to Italy in travel guide, we care about Venice. so, we have to use a restrictive relative clause starting with "that". i.e that contains references to Italy

Thinking on similar lines, now i am confused. How about saying -

, which contains references to Italy

i.e
Perhaps every travel guide , which contains references to Italy recommends that tourists, especially those in search of a romantic atmosphere, visit the uniquely beautiful, "floating" city of Venice.

At the time i started to express my thorughts, i assumed that i was clear on my thoughts, but while explaining my thoughts, i confused my self by adding "which" condition.

I am confused. Please help.

I believe both "that contains" and "containing" have the same relevance in these examples.

Only one is introducing a relative clause (that .....) , other is a present participial phrase (containing ...) / In fact you can convert a relative clause into a present participial phrase ,as you did with these examples ,without changing their meaning.
(not that these grammatical terms mean much - hope i am correct in identifying them as they are)

Both of them identify the same type of travel guide that is relevant in this context - the one that contains reference to Italy.
