BoundNotebook

•  Pagesaresewnorgluedtogether•  Advantages– Portable– Simpleset‐up– Common

BoundNotebook

•  Disadvantages– Noteasilysearchable– Requiresreferencetootherdata– Difficulttoduplicate– Requireslegiblehandwriting

Loose‐leafNotebook

•  “ThreeRingBinder”•  Advantages– Pre‐formatteddatasheets.

– Allowsprimarydatatobekeptadjacenttoexperimentalentries

Loose‐leafNotebook

•  Disadvantages– Noteasilysearchable– Easier,butstilldifficulttoduplicate– Requireslegiblehandwriting– Pagesmay“fallout”
