4) A video library lends videotapes to borrowers who must be authorised members. When videos are borrowed and returned, the library staff must place them back on the appropriate shelf for other people to borrow. Late returns are penalised with a fine. The library staff must keep track of fines due and those which have been paid. Videos which are worn or damaged and those which are no longer popular must be taken off the shelves. The library staff must search through catalogues of new releases which arrive in the mail to find videos which might be popular with the library's members. When these new videotapes arrive, they must be put on to holding shelves at the back of the store according to which one of several groups (e.g. children's, drama, comedy) they belong to. The library staff then create an entry for each new videotape in the catalogue database. The number assigned to the videotape in the database includes the copy number of the videotape where multiple copies exist. A sticker with this number is put on the videotape and it is placed on the shelves for borrowing.
