For more specific content of page, such as MicroformsAmericanFiction, I would suggest making these subpages of Microforms instead of creating separate pages. This will greatly help with organization as well as being able to automatically populate lists rather than having to do so manually.
On a side note, I noticed duplicate pages, such as AmericanFiction. If you intend to use the same material on two pages, I strongly suggest the use of the import function (transclusion), otherwise both places would have to be updated if anything ever changes.
Again, let me know if you have any questions.
