(The) Cambridge Dictionary. (A/The) Cambridge Dictionary('s) entry

[Alexey86]

there is only one Cambridge Dictionary, of which there are thousands of copies. The text itself is unique.

Even if "Cambridge Dictionary" functions as a physical object? I mean I found the bookmark in a book, not in the text if it matters at all.
BTW, I missed 'm' in "Cambridge"

Sorry, I misread your last question. I've just realised that you mentioned a bookmark, not a word.

In that case, your sentence is fine, although it is a very unlikely thing to say, as shown by your rather forced context. But yes, your thinking is correct.

(Sorry for any confusion caused on my part.)

That's the point! Since I don't have a native-like sense of English, I have to explore all possibilities. Thank you for your help!
