has just as much info as any other, especially technical information, but is sketchy on operational usage of the T-37. But does list some of the operations the T-37 was used.
Mainly T-37A as well as their brothers T-38 and T-40 were used in recon battalions of tank divisions in mechanised corps.
Most of them were lost in first months of the war due to low reliability and thin armor.
I can guess they were used in Neva landing operations near Leningrad (1941) and Svir' river crossing in 1944 (the last known usage of that kind of tanks as amphibious ones).
Also it's interesting to mention the 40th Tank Division/19th Mechanised Corps/South-western front had 139 T-37 "in addition" to its 19 T-26.
T-37 could be noticed in fights from the Crimea to Murmansk direction.
But due to operative situation most of them were lost in surface fights and because of different breakages, as they were shabby enough been produced several years before the war.
