The purpose of this thesis is to examine the classification,shelf arrangement and display of documents in antiquarianbookshops and see the reasons behind these. The results willbe compared with previous reviews of alternative shelfarrangement in Swedish public libraries, to see whatdifferences and similarities there are in the classification andshelf arrangement between antiquarian booksellers andlibraries. The questions to be answered were: (1)What formsof classification and shelf arrangement are used inantiquarian bookshops and how does it differ from theclassification and shelf arrangement made in libraries withan alternative shelf arrangement? (2)What exposure ofdocuments are there in the various antiquarian bookshops? Isthere anything regarding the exposure that differs betweenthe antiquarian bookshops and the libraries? An idea andideology analysis of various dimensions is used as atheoretical tool during the work. The dimensions were: (1)Shelf arrangement: It is important that customers/borrowerscan find themselves - it is important that staff know wherethe documents are.
