What is the correct way to quote this piece of text? The issues here are the initial letter which is now capitalized (I believe that is correct) and the omission of a few words near the period. Should the period still be present, should I remove it, is there any need for space there?
Original phrase:
This is how the clerk obtains user details and verifies its authenticity. Then, he is ready to proceed with the activation of the user account.
My attempts at it. Are these properly constructed?
[T]he clerk obtains user details ... . Then, he is ready to proceed with the activation of the user account.
[T]he clerk obtains user details.... Then, he is ready to proceed with the activation of the user account.
[T]he clerk obtains user details ... Then, he is ready to proceed with the activation of the user account.
[T]he clerk obtains user details ... [t]hen, he is ready to proceed with the activation of the user account.
Usually I read through OWL when I have these kind of doubts but I could not find anything regarding the specific case where you take out the words near the period but keep quoting right after it. I don't think it will matter but this is for a technical document.
