Luigi Bianchi: Modern LaTeX Working Editions and Source-Intake Witnesses

Dedicated Luigi Bianchi record for the Modern LaTeX Editions of Mathematics Manuscripts project. This record contains Italian source transcription, English translation working drafts, source scan witnesses, and auditfix packages for Bianchi's differential-geometry and transformation-group texts. Status at a glance. Volume I of Lezioni di geometria differenziale remains complete as a package-audited Italian/English working edition through source pdfpages 001-543. The A2 branch, Lezioni sulla teoria dei gruppi continui finiti di trasformazioni, remains in progress. OCR/image-analysis material is witness/locator evidence only; source scans and package audit ledgers control mathematical readings. Latest update. Adds Bianchi_A2_cont_p0001_0066_IT_EN_20260611.zip. This package continues from the p0001-p0057 audited layer, restores the deferred beginning of section 10 on source p0057, and continues through complete sections 10, 11, and 12 ending at the top of source p0066. It includes Italian/English current-slice and cumulative TeX/PDF, source-witness PDFs, high-detail page PNGs, contact sheets, formula/page ledgers, render checks, and clean build logs. The section 13 heading and first line visible lower on p0066 are intentionally deferred to the next work unit. Corrections and collaboration.
