Same text, same edition, very different books
A great example of why we collect multiple copies:
This is a theological work on Unitarian Christianity from 1787, and AHTL holds four copies. The images above are of copies 2 and 3. Both have important provenance demonstrating historical connections between American and Transylvanian Unitarians.
Copy 2 was presented to AHTL in 1922 by a Unitarian Bishop from Kolozsvár; copy 3 was received via the American Unitarian Association, to whom it was given in 1955 by the chairman of the Budapest Unitarian Congregation “as a symbol of fraternity.”
Szentabrahami, Michael Lombard, 1683-1758. Summa universae theologiae Christianae secundum unitarios, in usum auditorum theologiae concinnata et edita. Cum privilegio sacr. caes. reg. apost. majest. Claudiopoli : Typis Collegii Reformatorum, 1787.
This unassuming octavo is a 1652 copy of John Hoddesdon’s compiled Tho. Mori vita & exitus, or, The history of Sr. Thomas More, sometime Lord High Chancellor of England. Hoddesdon was an unsuccessful writer and later turned to trade in 1658. His life of Sir Thomas More was reissued in 1662 perhaps to pay off his debt (Hodson, ODNB). Apparently Hoddesdon’s book is not as thorough or complete as the reader thought it should have been (or maybe he really was just a terrible compiler). The last leaf of the book features additional witty sayings by Sir Thomas More left out by Hoddesdon. The reader did not make any other notes—only adding his or her thoughts at the end.
