1) If you want to alter what tags are mandatory when adding a bibliographic record, you will have to edit your MARC structure. You can do this through: System Preferences / MARC Bibliographic Framework. Then click on the 'MARC Structure' link for the framework you want to change (probably 'Default'). From there, click the 'Edit' link for the tag that you want to make non-mandatory. Then untick the 'Mandatory' box and save your changes. 2) The '+' symbol at the end of every subfield allows you to enter a second field attached that particular subfield. For example, if a book has two authors, you can click the '+' next to 100a to add a second author. Hope that helps!
