### 1. Field books

Individual project field notes are generally subsets of a larger series of survey operations and contained in field books. Three main field book types are defined by their method of holding pages together, Figure C-1:

• Book - Uses a sewn or glued binding; hard- or soft-cover.
• Spiral bound - Pages are held together with a spiral or comb metal binding which allows the book to be folded back on itself for easier note taking.
• Binder - Loose-leaf pages are held together with two sets of three-ring clips. Its advantage is that the pages can be removed for filing after project completion and can reused with additional paper.
