When possible, it is best to arrange book-length manuscripts according to the stages of the work (see Appendix A: The Creative Process). For less extensive writings files, the same principle of arrangement can be followed, as best as can be determined, with various stages of the work arranged in the order in which they were created.
The level to which The Creative Process guidelines are applied to materials relating to individual titles is flexible and should depend on the material, original order, and anticipated research use.
Materials related to writings, physically and conceptually, are often found mixed with other materials in the collection. These materials can usually be left in non-writings series.
