The “original” records are a mish-mash of originals, eighteenth-century copies, nineteenth-century copies, interpretations, abstracts, re-interpretations, and so forth, so it is understandable that no one has tackled their consolidated publication. These days, they are available through Internet sources – provided one is determined enough to look them up.
The entire collection of records was microfilmed by the LDS Library and has been available for many years, but it has recently become searchable (to an extent; the index often contains errors) on Ancestry.com through a newer filming by Jay and Delene Holbrook entitled Massachusetts, Town and Vital Records, 1620-1988. NEHGS has a completely separate copy of some of the records made by Reuben Hersey between 1832 and 1844 that is searchable on AmericanAncestors.org. The oldest records come from the Rev. Peter Hobart’s journal, published serially throughout Volume 121 of the Register, and also available on AmericanAncestors.org. However, this is a compiled collection from various transcriptions, the tortuous provenance of which is detailed in the introduction to the article, and when compared to microfilmed versions can be quite different.
To do a comprehensive search of Hingham records one must compare Lincoln’s History, the published Hobart Journal, and all of the digital versions, which do not always agree. Lincoln’s version is the least reliable.
Oh, yes, then there is the problem of counties. Hingham is presently in Plymouth County, but it was originally part of the Massachusetts Bay Colony, so its earliest probate and land records, from 1643 to 1793, are in Suffolk County. From 1793 to 1803, they are in Norfolk County, and thereafter in Plymouth County. Not to mention that the eastern part of Hingham was split off to become Cohasset in 1770 and is still in Norfolk County!
Eleanor Roosevelt once said Hingham’s Main Street was the loveliest in the country, but she never had to deal with the records.
