## A. Items requested but NOT found as described (do not cite in that form)

| Requested item | What was searched | Outcome |
|---|---|---|
| Hill, R. J. (2025/2026) survey in *Journal of Economic Literature* or *Journal of Economic Surveys* | Crossref bibliographic queries on "Hill survey real estate price measurement"; web search of JEL/JES; University of Graz publication list; RePEc profile phi55 | **No such JEL/JES paper exists.** The latest Hill survey is Hill & Steurer (2026), "Real Estate Price Measurement Since the Global Financial Crisis: Methods, Data and Policy Developments", *Review of Income and Wealth* 72(1), article e70055, DOI 10.1111/roiw.70055 (verified; key `hill2026survey`). The earlier survey is Hill (2013), *JES* 27(5), 879–914 (verified; key `hill2013survey`). |
| Hill, Scholz, Shimizu, Steurer RTD paper "in JREFE or similar" | Crossref | Found in *Journal of Official Statistics* 38(1), 2022, 127–151, DOI 10.2478/jos-2022-0007 (verified; `hill2022rtd`). Not JREFE. |
| Ishaak, Ouwehand, Remøy, **de Haan** (2023–2024) HMTS paper, "possibly JOS or Real Estate Economics" | Crossref (author + "hedonic multilateral time-series"); CRAN `REPS` and `cbsREPS` reference manuals; web search; SAGE page (403) | The published source of the HMTS method is **Ishaak, Ouwehand & Remøy (2024)**, "Constructing Limited-Revisable and Stable CPPIs for Small Domains", *JOS* 40(3), 380–408, DOI 10.1177/0282423X241246617 (verified via Crossref and attributed as the HMTS source by the official CBS `REPS` package manual; `ishaak2024hmts`). The `REPS` manual also cites a four-author "Ishaak, Ouwehand, Remoy & De Haan (2023)" without title, venue or DOI; **no bibliographic record of that 2023 version was found** (not on Crossref, not on CBS/Eurostat pages reachable). Cite the 2024 JOS article. Note the empirical application is to Dutch *commercial* property (CPPIs), although the method is generic. |
| Diewert (2005) "on house price indices" | Crossref | Diewert's 2005 papers are on index-number theory, not housing: *RIW* 51(4) (weighted CPD regressions) and *Annales d'Économie et de Statistique* 79/80, 759–786 (adjacent-period time-dummy hedonic regressions, DOI 10.2307/20777596). The latter is the one relevant to time-dummy HPIs and is included (`diewert2005adjacent`). No 2005 Diewert paper specifically on house price indices was found. |
| Diewert (2010) "Alternative Approaches to Measuring House Price Inflation", UBC DP 10-10 | RePEc ubc:bricol; UBC faculty PDF `dp1010.pdf` (HTTP 404 on 2026-10-21) | RePEc lists the paper with **year 2011** (handle `erwin_diewert-2011-1`, "revised 07 Jan 2011"); CitEc also indexes it as `erwin_diewert-2010-26`. The DP number 10-10 is inferred from the PDF file name only. Included as `diewert2011alternative` with a note; cite as 2011 or verify from a surviving copy of the PDF before citing as "2010, DP 10-10". |
| Syed, Hill & Melser (2008) UNSW working paper "Flexible Spatial and Temporal Hedonic Price Indexes…" | Crossref | Found only as an SSRN posting (DOI 10.2139/ssrn.1313693) with author order **Hill, Melser, Syed** (2008).

| Bank of Canada documentation on Canadian house price indices | Two targeted web searches (`site:bankofcanada.ca`, "staff analytical note", "Financial System Review", Teranet, MLS HPI) | **Nothing found.** No Bank of Canada staff note/discussion paper comparing Canadian HPIs surfaced. Not cited. |
| CMHC documentation on a house price index methodology | Web search | **Nothing found.** CMHC does not appear to publish an HPI methodology document (its Housing Market Information Portal republishes third-party indices). Not cited. |

## B. Items verified but with metadata caveats carried into the JSON `notes`
