As I thought, the NYSE/NASD data includes hedge funds:

Similarly, hedge funds are subject to the same disclosure obligations as other market participants with regards to short sales. While the Commission's rules generally do not require the disclosure of most short sales or short security positions, rules of self-regulatory organizations require their members to report once a month aggregate short positions in exchange-listed and Nasdaq securities to all customer (including hedge fund customers) and proprietary accounts. This information is publicly available.

[...]

SROs require members to report short positions in all customer and proprietary accounts and aggregate information, by security, is published monthly.
