The LDS Newsroom is reporting that after the new handbooks are released tomorrow, they will be available online:
The handbook includes two volumes, one of which will be provided to hundreds of thousands of men and women who shoulder significant responsibilities in administering local Church programs and congregations. It contains the vast majority of revisions and will be posted online Saturday at lds.org, the Church’s website for members, where anyone can view it. Complete video of the worldwide leadership training broadcast will also be posted online late Saturday evening, Mountain Time.
Apparently Book 1 will be available online for Bishops and Stake Presidents only
