Booksellers engage in selling books to a variety of customers, from school children to teachers, government office to businesses, sportspersons to politicians, and economists to historians. They generally possess a sound knowledge in different types of books, their authors and edition. Besides, they remain familiar with the total stocks available in the shop. Booksellers may also sometimes offer advice on the kind of books required for a specific need. Like in many fields, a bookseller’s salary also goes up with experience. Work location and type of the company are some of the other factors which play a vital role in determining the income. On average, a bookseller earns to the tune of $35,000 annually.
