PREFACE (2025 ONLINE EDITION)

Converting this book into a modern online edition posed some interesting challenges. First, many of the images contained in the book were spread across two pages. The PDF scan of the book that I worked with did not include a properly merged image.

Sample two-page graphic illustrating the issue.

I am acquiring a physical copy in hopes that I might be able to better recreate those images.

The second challenge is a bit more subtle but equally important to me, the accessibility of the content of the information that is contained in the technical drawings. Many of the drawings have callouts or even complete tables of data.

Sample graphic with embedded callouts.

I am researching best practices for how to make the information accessible to all.
