Why This Source Was Added

Earliest book-form AC symbolic-method source; essential for edition comparison against the later 1916 source already processed.

Candidate processing state

• Source type: book_edition
• Internet Archive identifier: theoryandcalcul03steigoog
• Generated section records: 30
• Candidate equations: 300
• Candidate figures: 32
• Candidate quote hits: 0
• Review status: OCR-derived candidates, not a corrected critical edition.

Edition And Custody Note

First edition; Open Library lists this Internet Archive item for the 1897 W. J. Johnston edition.

The PDF/page images remain the verification base. The archive has preserved the Internet Archive OCR and generated candidate catalogs so this source can now participate in search, source-text browsing, concept concordance, theme evidence, and chapter workbench pages.

Promotion Path

1. Verify title page, edition, and publication metadata.
2. Correct the section map if OCR headings caused false splits.
3. Scan-check equations and diagrams before promotion.
4. Add modern engineering explanations only after source passages are anchored.
5. Keep edition differences visible when comparing related Steinmetz works.

What This Source Currently Gives The Archive

Theory and Calculation of Alternating Current Phenomena currently contributes 30 processed sections and 76,757 candidate OCR/PDF-text words to the archive. Its strongest tracked evidence clusters are Impedance / reactance, Magnetism, Waves / transmission lines.

This is a routing judgment based on processed metadata, not a final historical claim. The strongest next move for any exact quotation, equation, or diagram is still to open the source scan and check the page image.

Verification Focus

Source custody

Verify title page, edition, page images, and OCR line boundaries before final quotation.

Mathematics

Use the formula map to locate equations, then correct OCR symbols and preserve Steinmetz notation before modern translation.

Interpretation boundary

Modern engineering and ether-field readings belong after source anchoring, with labels kept visible.
