circulation - The process of checking books and other materials in and out of a library. Also refers to the total number of items checked out of a library by borrowers during a specified period of time, and to the number of times an item is checked out during a fixed period of time, usually a year. Low circulation is often an important criterion in weeding a collection. Books for which circulation is anticipated to be high are sometimes ordered in multiple copies to satisfy demand, or given a more durable binding to withstand heavy use. Some online circulation systems provide circulation statistics broken down by classification for use in budgeting and collection development. Circulation is fundamental to access services. ; дс тдрлими цюлютдажкию дроемжки аиакиохдйис лидр http://vax.wcsu.edu/library/odlis.html;
