Mineral composition of 356 sediment profiles from the Arctic seas

This data set contains the mineralogical analyses (binocular counting) of the 100-50 µm grain size fraction from bottom sediments collected by scientists of the V.P. Zenkovich Laboratory of Shelf and Sea Coasts (P.P. Shirshov Institute of Oceanology, Russian Academy of Sciences) during the Project ''Arctic Shelf of the Eurasia in the Late Quaternary'' in a number of expeditions to the Barents, Kara, East Siberian and Chukchi Seas on board research vessels R/V Professor Shtokman, H/V Dmitry Laptev, H/V Malygin, and icebreaker Georgy Sedov between 1978 and 1990. The analyses have been carried out according to the methods published by Petelin V.P. (1961) in the Analytical Laboratory of the P.P. Shirshov Institute of Oceanology. Archiving and electronic publication was performed through a data rescue by Evgeny Gurvich in 2003.

Deeds for properties in Boston [and Cambridge?], 1798-approximately 1945 (inclusive); approximately 1880-1920 (bulk)

This group of records contains deeds and related documents for a selection of properties owned by Harvard University in Boston and possibly Cambridge and other nearby communities through the mid 1940s. Documents include deeds, assignments of mortgages, receipts, correspondence, and other legal documents. Many of the documents record property transfers prior to Harvard's acquisition of the property, and often the documents do not fully identify Harvard's involvement with the property. The bulk of the documents date from the late 19th and early 20th centuries.
