[Rather than a mere Diary Caroline Weasley has probably what resembles a scrapbook if it were bound together or if she was organised to do such a thing. It is instead a folder with ribbon tied around it that lives in an old lidded box. It is a rather eclectic collection of newspaper articles, or items she has found and wants to keep, and includes quite a bit of loose leaf parchment - from things that she has copied from things she has read (as either "handwriting practice" or because she liked it and wanted a copy), loose leaf diary pages, notes and observations along with her own special project - her own zoological diary and other things she had decided to write down, plan or keep.]

To the standard observer it is mostly a chaotic mess and Caroline would love to say she knows where everything is...................  she probably does not but swears she puts everything in it and totally does.
