You have to be careful not to be attracted by the variety of books in a bookshop.It is very easy to enter the shop looking for a book on,say,ancient coins and to come out carrying a copy of the latest best-selling novel and perhaps a book about brass-rubbing (拓印品)—something which had only vaguely interested you up till then.This volume on the subject,however,happened to be so well illustrated and the part of the text you read proved so interesting that you just had to buy it.This sort of thing can be very dangerous.Apart from running up a huge account,you can waste a great deal of time wandering from section to section.Booksellers must be both long-suffering and indulgent（纵容地）.
