Brianna received six new books and bought eight new books, so she has a total of 6 + 8 = 14 new books.
She plans to borrow two fewer new books than she bought, so she plans to borrow 8 - 2 = 6 books from the library.
In total, Brianna has 14 + 6 = 20 new books.
Brianna reads two books a month, so in a year she reads 2 x 12 = 24 books.
She wants to have a total of two books to read each month this year, so she needs 2 x 12 = 24 books in total.
She already has 20 new books, so she needs to reread 24 - 20 = 4 books from her old book collection.
Therefore, Brianna needs to reread four books from her old book collection.
#### 4
The answer is: 4
