The CD-ROM provides: Boolean and proximity searches; complete text search; extensive support for bookmarking, journaling and annotation; interlinks leading to related topics and examples; zoom features for detailed viewing of figures and graphs; cut and paste capabilities for inserting text into other documents and programs; and an expandable table of contents providing instant access to text, tables and illustrations. Besides the complete 25th edition, this CD-ROM also contains important material from earlier editions of Machinery's Handbook. Extensive cross-referencing between the CD-ROM and Handbook make them ideal complements and the COMBO Specials a great value.
