Dear Sirs,

I am writing because I want to enroll into your library and would like to know more details about it.

The first thing that interests me is if you have any books about computer science.

I would like to know also if I can use the library even though I'm not from London, and if I can then how can I do it.

Another thing that I would like to ask you about is how much will I be paying for belonging to library and for borrowing books.

Finally, I would like to ask If I can use the library via internet and if there is such a possibility, how can I do it.

I am looking forward to your answer.

Yours faithfully,
XYZ

O mój boże! Napisałem "dir" zamiast "dear" .

Dziękuję bardzo za pomoc.

EDIT: Jeszcze jedna rzecz a mianowicie słówko enroll. U mnie w słowniku jest coś takiego "enrol (US enroll)". Czy jeśli uczę się britisha to nie powinienem użyć tego z jednym "l"?

co do tego to nie mam pojecia, ale zawsze odnosilam wrazenie, ze enroll sie pisze przez dwa ll

Dear Sir or Madam,
I am writing to ask about details of borrowing books in your library. My first question is if the library possesses any psychological books or magazines? I am really interested in that field. Secondly, I would like to know of and in which way I could use the library living outside London? (I live in Swanley) What is the cost of being a member of the library and the cost of borrowing books or magazines? At the end I would like to know if there are any pissibilities to use the library via the internet? If so, in what way I can use it?
Thank you for your consideration. I look forward to hearing from you.
Yours faithfully
XYZ
