Esperanto in Scotland, Chapter 1, Exercise 3
Sample answer: three of the kinds of source named in the chapter.

1. Letters and postcards (John Beveridge Collection)
   Made by: the people who took part, writing to each other.
   Why: to keep in touch and share news, not to write history.
   Trust: good evidence of friendships and attitudes, but only for the people whose papers survive.

2. Scottish newspapers (Dundee Advertiser, Courier, Evening Telegraph)
   Made by: journalists and club secretaries sending in reports.
   Why: to announce meetings and report events, often to encourage people to join.
   Trust: useful for dates and names; membership figures and descriptions of success may be promotional.

3. Esperanto periodicals (The British Esperantist, La Revuo)
   Made by: movement editors and correspondents.
   Why: to inform and encourage members.
   Trust: good for how the movement saw itself; check figures against another source.

A good answer gives, for each source, who made it, why, and one limit.
