"Love Letters of Great Men", which Carrie borrows from the library, was a prop created for the film and no such book existed during production. Demands from fans wishing to purchase the book led to many editions of a "Love Letters of Great Men" book being published. The official tie-in version was compiled by John C. Kirkland and released the same day as the film, and other editions were compiled by Ursula Doyle and Becon Hill.

Carrie returns books to the main branch of the New York Public Library. That branch has not been a lending library for more than 60 years.

An extended version version exists. While it shortens a few shots, collectively, by about 2 seconds, it adds about 5 minutes. The major additions are - 1. When Carrie tries on her outfits before she leaves her apartment, the rest of the girls, including Lily, try on her outfits as well. 2. Right before Carrie leaves the apartment, she disconnects the computer. 3. Carrie walks through the Mexican house alone for a bit. 4. When Miranda find her new apartment, she goes in, looks around and tell some guy that she is interested in it. 5. Following the scene where Samantha and Smith have sex and talk about Samantha feeling distanced, she and Carrie talk on the phone - Carrie is using a public phone - and Samantha tells her she will be coming much less to New York in order to take care of her relationship with Smith and Carrie is surprised. 6. Following the scene where Carrie buys the Vogue issue, she meets with Charlotte and they go trick-and-treating together with Harry and Lily and a neighbor shows her condolences, which makes Carrie wear a mask for the next door. 7. Following the scene where she types "Love..." on her laptop, Stanford calls and invites her to a party where he is bored and she declines.
