The Anomaly Outlived Its Planet: third-party sources and their terms
======================================================================

This page ships three small JSON files it made itself: transcribed numbers, short quotations and modern
constants, each with its source. It ships no scan, page image or publisher file. Every source is named below
with the terms under which the page uses it.

1. U.-J. Le Verrier, Théorie du mouvement de Mercure, Annales de l'Observatoire impérial de Paris, Mémoires,
   tome V (1859), pp. 1-196. Read from the NASA ADS scan:
     https://articles.adsabs.harvard.edu/pdf/1859AnPar...5....1L
   The work is of 1859 and its author died in 1877. The ADS terms (https://adsabs.harvard.edu/use.html) say
   that full-text articles "are copyrighted by the respective publishers" and that "the reproduction of
   full-text articles or abstracts requires express written permission from the publisher". The page therefore
   ships only the numbers of pp. 79-100 as transcribed facts (leverrier-1859.json) and short quotations, cited.

2. Comptes rendus hebdomadaires des séances de l'Académie des sciences, volume 49 (1859) and volume 50 (1860),
   Internet Archive items marked "Public domain. The BHL considers that this work is no longer under copyright
   protection.":
     https://archive.org/details/comptesrendusheb49acad
     https://archive.org/details/comptesrendusheb50acad
   Used for short quotations of Le Verrier's letter to Faye (vol. 49, pp. 379-383) and of Lescarbault's letter
   and Le Verrier's remarks (vol. 50, pp. 40-46), and for Le Verrier's 1860 figures in reference.json.

3. Simon Newcomb, Discussion of Observed Transits of Mercury, 1677-1881, Astronomical Papers prepared for the
   use of the American Ephemeris and Nautical Almanac, vol. 1, part VI (Washington: Bureau of Navigation, Navy
   Department, 1882). Internet Archive item marked NOT_IN_COPYRIGHT (a Google scan; its preface asks for
   non-commercial use of the scan files, none of which the page ships):
     https://archive.org/details/astronomicalpap00newcgoog
   Transcribed numbers from pp. 457-473 (newcomb-1882.json) and short quotations.

4. A. Einstein, Erklärung der Perihelbewegung des Merkur aus der allgemeinen Relativitätstheorie,
   Sitzungsberichte der Königlich Preussischen Akademie der Wissenschaften zu Berlin, 1915, pp. 831-839,
