Code:

public void ShowBooks()
{
    for (int i = 0; i < books.Count; i++)
    {
        Console.WriteLine("Title: " + books[i].title + ", Author: " + books[i].author);
    }
}

public void FindBook(string t)
{
    for (int i = 0; i < books.Count; i++)
    {
        if (books[i].title == t)
        {
            Console.WriteLine("Found: " + books[i].title + " by " + books[i].author);
            return;
        }
    }
    Console.WriteLine("Book not found");
}

Description:
Both methods ShowBooks() and FindBook() have almost the same loop for iterating books.
This violates the principle of DRY, because the data access logic is repeated.
