The 2017 Hugo Voter Packet is available for download by members of Worldcon 75. “Messages have gone out to voters, including personalized links and information on how to access the packet. Anyone who has not received it should contact firstname.lastname@example.org.”
The packet does not contain all the nominated works in their entirety, but there is some free material in most categories. The voting packet will be available for download until July 15, 2017, when voting closes.
For more information, see the Worldcon 75 post.
