The job duties of a tape librarian revolve around working to catalog and maintain computer tapes for a library. Your responsibilities in this career include assessing reels and cartridges and recording them according to the subject, content, users, and other variables. You may complete this process by comparing the tape’s data to that of other tapes in your library. You then assign the proper code to the tape so that users can locate it based on its identifying features. You may scan returned tapes to assess the condition and recommend repairs or removal from circulation.
