Any record information (spectra, trees, chromatograms, structures and compound identification information) can be changed and saved in library. If anything is changed in the record a small circle is displayed in Database Manager in the ID Num. column in the spreadsheet. Changes in records are not automatically updated in database unless you save them.

To save changes in library please choose Library | Spectral Library | Save Changes in Library in main menu item.

If you try to save a newly created record, you will be redirected to the Add New Records to Library option.
