Effective January 1, 2018, the frequency of the CD-ROM updates will be reduced from the current bi-monthly mailing to a quarterly mailing. This change will mean that you will receive four CD-ROMs each year instead of the six that you receive under the current procedure.  We will continue to post documents published between CD-ROM mailings to our website so that you may access them through your subscription login.

If you have an active subscription to the Hartzell Technical Documents Library on CD ROM, you can log in here to get the documents that are published between issues of the CD ROM.
