This section includes letters of support and congratulation, opposition and excoriation, appeals for assistance and employment, letters of recommendation and introduction, and such like material. A sample of the (carefully filed) letters from individuals deemed 'cranks' has been retained, as has a quantity of the largely ephemeral letters from seekers after autographs and signed photographs. Dealing with these consumed the time of the private office and private secretaries, as did more obviously important matters, but good manners and good public relations demanded that reasonable requests be met. The classification of 'crank' was used relatively infrequently. The index includes only the more significant correspondents.

Some stray items will be found in Charities, Patronage, and Memberships and in previous sections relating to invitations and engagements, which overlap with the current section. See: MSS. Welensky Papers 280/7-283/6 for actions at law leading to the award of damages to Welensky and his subsequent donations to charity; and MSS. Welensky Papers 27/1-30/5 for further material on the Rhodes Centenary.
