All handbooks are taken from the original documents. The results are cleaned to remove oil stains, fingerprints and the fading associated with ageing. The pages are then fully indexed and made searchable. Links are built for fast cross referencing to diagrams and other references.
Every handbook is in the industry standard Portable Document Format (pdf) and can be used on MS-Windows, Apple IOS, or Android computers, tablets or smart devices which support Adobe Reader or compatible software.
