Library Film & Video Collection Student Assistant Manual

Library Terms


Storage facility where all of Film & Video’s 16mm film collection and most of its VHS are stored.  Material can be retrieved from the Annex by submitting an online form found on the F&V homepage. Items are brought to Morris Library once each weekday.


A barcode is a 14 digit number starting with 317411…assigned to each item, usually located on the inside (or sometimes back) of a DVD case.

Blu-ray (HDDVD)

Blu-ray is a digital optical disc format designed to display high definition video and store large amounts of data.


Film & Video offers a booking service so that professors wanting to schedule films for class viewing may be assured that the material is available for them to use on the date they need it. The booking system is only available for UD instructors.  The online form is on the F&V webpage. Material must be scheduled 7 days in advance.

Call Number

A call number consists of a series of letters, numbers or symbols that identifies an individual book or material and shows the order in which the item is stored on a shelf or in a collection of materials. The call number label is usually located on the spine of a book. A call number in F&V consists of letters and a number that identifies the format (DVD, Blu-ray, etc.) and shows the order in which the item was added to the Collection. The call number label is usually located on the spine of a case but can also be found on the front.  

Check Out

In order to borrow material from the library, patrons must have it charged out to their name using their UD I.D. or public borrowers library card.  This is called a “check out”. The user is given a due date, by which the item should be returned to the library.

Discharge/Check In

When a patron returns an item to the service desk, we discharge it or check it in.  This removes it from their account.

Due Date

The due date is the date by which library materials on loan should be returned. Loan periods range depending on the status of the user. Materials not returned by a designated due date are subject to fines.


Stands for "Digital Versatile Disc", a type of compact disc able to store large amounts of data, especially high-resolution audiovisual material.


Online Computer Library Center is “a global library cooperative that provides shared technology services, original research and community programs for its membership and the library community at large.” (


Replace material on the shelf where it belongs, taking care to be sure it is in the proper place.

Streaming Media/eVideos

Titles that are available to watch online.  The Library subscribes to streaming media databases, which can be accessed by University of Delaware students, faculty, and staff.  These titles can be found in DELCAT as eVideos with a “View Now” button. They can also be accessed from the F&V homepage by clicking “Streaming Media”.


Users must present their UD I.D. to borrow material.  Other types of I.D. that may be used to view material on site are: I.D. from Delaware Technical and Community College or Delaware State College; a public borrower’s card. If a user does not have proper ID, ask Staff to help them.


Video Home System (VHS) is a storage media standard used for analog recording and distribution of media through magnetic videotape cassettes.  There are a small number of regularly used VHS in F&V’s on-site shelving and some in the Library’s off-site storage facility, the Annex.  DELCAT will indicate in where each VHS is located.


A disc used to store visual images.  In Film & Video, this will most often refer to a LaserDisc, which was the first commercial optical disc storage medium. Although the format was capable of offering higher-quality video and audio than its consumer rivals, VHS and Betamax videotape, LaserDisc never managed to gain widespread use in North America, largely due to high costs for the players and video titles themselves and the inability to record TV programs.


Worldshare Management System is the software used to create DELCAT Discovery, and is used to facilitate many facets of Library business.
