I have chosen to spotlight this CD of books by and about HPB:

Theosophical Classics CD

http://www.seekerbooks.com/media/9780835619509.htm

This CD contains:

The Secret Doctrine
Isis Unveiled
Key to Theosophy
Voice of the Silence
The Complete 15 volume Edition of H.P. Blavatsky Collected Writings
Theosophical Glossay
and Transactions of the Blavatsky Lodge

The great thing about this CD is that it contains the 15-volume Collected Writings:

If anyone has ever used this 15-volume set, it is, well, heavy, and takes up one whole shelf! To get all of this on a single CD makes it much more convenient than using the hardcopies.

The CD is also searchable, so people doing research will find it much more easy to use than the hardcopy books.

And now it's online! (or those 15 volumes are):

Blavatsky's Collected Writings

A bit late - it's no longer online. Anyhow, great CD.
