The rule you talk about is accusative, which is only usable when the noun is an object to the sentence. 'books' is the object of the english sentence, but kitaplar is the subject of the Turkish one, so no accusative possible on it. Which means, depending on context, it can be "some books" or "the books".
But, as explained very well and in much detail by someone else in another question from this lesson (don't know how to find it though, but do check the discussions), when in turkish you choose this locative construct (literally "books are with me") it is very very likely that they are books in particular, not just 'some books'. If it were 'some books', you would use the 'var' type of construct, ie -and i hope i dont make a mistake here : kitaplarım var, literally there is such a thing as my books = i have books. Hence:
- i have a/some thing --> (my thing) var
- I have the thing --> (thing) bende
I just learnt this, would be great if someone more knowledgeable could check and correct me if i'm very wrong
This case seem confusing to many because of the use of 'have'. When translating these sentences I mentally add 'here' to the sentence. Ördekler bende = I have the ducks (here). This emphasises the fact that I am using the Locative case. Later on this way of thinking may not apply but for these simple sentences it helps to get your head around the locative case. Hope this helps a few people.
Kitaplar bende: I have the books./The books are with me. Kitaplarım var: I have books.
I guess the problem is about different meanings of 'have'. In first sentence it means something like ''I am the last one getting the books so they are with me now.'' But in the latter one its meaning would be ''There are books which are in my possesion.''
Where from comes The? If the example is right,then how cam I say Yes,I have books? In fact,I have strong belief that such construction should be translated as The ball is on my side ...It is me,who has the books/books. Not just I have apples,which is Ben elmalar var or even Bende elmalar var,but no way Elmalar bende. Elmalar bende sounds like It is me who keeps apples....See the concept? Bende para yok means I don't have money on me (handy). If you don't have it at all,use Ben parasîz ( I'm moneyless) No proper font,sorry in parasIz
There is no such a sentence as 'Ben elmalar var.' And
I have books: Kitaplarım var.
I have the books/ The books are on me: Kitaplar bende.
Bende elmalar would be used in a sentence like: 'Bende elmalar var, sende armutlar var.'(I have (the) apples, you have (the) pears.).
