==Construction== Stockbooks consist of a number of stiff pages, made up with horizontal pockets of manilla paper, glassine paper or clear film, into which stamps are placed. Collectors can insert stamps side by side in a row or can overlap stamps when individual viewing is not necessary. The pages, usually double-sided, are bound into book form. The most popular sizes comprise between 4 and 32 double-sided pages with each page interleaved with a glassine, or clear, sheet to prevent stamps on adjacent pages from touching.
