The Thought Book (variant: red, 500-page notebook made from the finest writing paper, specially designed for use with fountain pens) is aimed at professional writers: book authors, journalists, intellectuals. It features several characteristics that facilitate creative work and particularly the subsequent exploration of its content. If you are working on multiple topics simultaneously, four differently colored bookmarks will help you quickly locate your current writing position. You don’t have to fill this notebook sequentially; instead, you can work on various topics throughout the entire book at the same time. This is made possible by the structured table of contents, where you can later add content under different topic or project headings. To quickly access handwritten content later, each page includes a keyword line and a date field, as well as a status line at the top margin, where you can mark a sequence of scattered parts or evaluate different versions under any keyword you have worked on in multiple places in the book. At the bottom, there is also a slightly separated area for footnotes or you can simply overwrite this area. The back cover contains a spacious, very easy-to-use pocket for supplementary documents.
