Scrolling idly through the SOAS Library’s subject catalogue, I must have brushed an unusual combination of keys, so activating a random function not mentioned on the options bar nor widely known to researchers. The feat has since proved impossible to repeat. But I keep trying; for it was thanks to this truly serendipitous action that up flashed a title which, for its crystal candour, can seldom have been bettered. Fish and Fish Dishes of Laos was so specific it had to be just that – a handbook and culinary guide to the fish to be found in landlocked Laos. The author was Alan Davidson, the publisher Prospect Books, the category ‘Long Loan’, and the status ‘Available’. Like a minnow into the reeds, I darted to the stacks.
