These two databases provide addresses, phone numbers, focus, and quarterly or monthly returns depending on how often the fund reports and what level of database subscription you pay for. You should also note that no database will be comprehensive, because the funds aren't required to report to anyone and often don't if they're closed to new capital.
You'll have to shell out some cash or find a friend in the industry that will share if you want these databases.
