This process is done after you have searched thoroughly and found no existing bib record for you to link an item record to. If you find a bib record for your title, see Cataloging- Creating an Item Record.
Within Sierra’s Catalog function, click on the New button.
A Bib record template will open and you will be prompted to fill in certain fields to help the MHLS catalogers identify the title and find a more comprehensive, robust bibliographic record.
When you have filled in as much information as you can provide (you may not know all of the information) click on the Save button to submit the record.
