Heinrich Weber, Lehrbuch der Algebra: German LaTeX and English Translation Working Drafts

Dedicated Heinrich Weber record for the Modern LaTeX Editions of Mathematics Manuscripts project. This record contains German modern-LaTeX transcription and English translation working drafts for Lehrbuch der Algebra, with source-scan repair packets and cumulative readers. Status at a glance. Volume I is complete as a repaired/source-scan-audited working edition. Volume II remains in active repair and continuation, with the current cumulative reader rebuilt through section 176 and selected earlier gaps replaced by source-scan-backed repairs. Volume III remains the current repaired cumulative from the earlier baseline. OCR files, marker scans, and display ledgers are omission guards and locator layers, not independent textual authority. Some inherited cumulative material still carries marker terms such as summary/summarized and should be checked package by package. Latest update. Adds Batch121. Batch121 is a corrective packaging and continuity pass for Batch120, not a new content-repair claim. Batch120 paired non-contiguous Volume II section 106 and section 114 repair slices in a way that made the inspection PDF appear to jump over sections 107-113. Batch121 splits the section 106 and section 114 repair PDFs/TeX into separate section-level artifacts and adds contiguous cumulative extract PDFs/TeX for sections 106-114. Its issue ledger confirms sections 106-114 are present in order in both German and English cumulative Volume II. The cumulative Volume II text is carried forward from Batch120 for these sections because the continuity check found the sections already present. The active repair ledger remains 19 of 112 rows closed and 93 open, with all tier-3 rows closed. Next suggested repair route: Volume II sections 71 and 81, then remaining lower-tier Volume I rows.
