Which do you prefer? Short stories? Or full-length novels?
Usually I prefer full-length novels - or even series of novels - with time to get to know the characters. I can enjoy short stories too; but I often find it hard to plough through a collection of a lot of various short stories in a short time, unless there is something to tie them together - like the same characters, or a common theme. When I have little time to read though, short stories might sometimes be just the thing.
Looking at my own book shelves, I have a lot of novels, but few collections of short stories. In English, I have one paperback collection of 50 Great Short Stories by various English and American writers, which I bought once in a second hand bookshop. I also have a book of "Eerie Tales" which I bought in Britain back in the 70s. I think I might have bought it when we were up at Loch Ness in Scotland, but I'm not quite sure. There is also a Penguin Classics collection of stories by Edgar Allan Poe, a Wordsworth Classics collection of Father Brown stories by G.K. Chesterton, and The Case Book of Sherlock Holmes. I also have several versions of King Arthur tales; and at least four more recently bought books with Celtic Myths and Legends, like the Mabinogion. I have not read all of these through, just looked things up and read some of the stories.
