types of material/headings

Hi Adena,

I enjoyed reading your wiki! A few suggestions I have: perhaps beside Types of Material, you could give a link to a prominent example? I'll second Allison's comment below about expanding that section, or else those types of material do not seem unique to archives in general. Also, your section "Position in Archival Theory" is block heavy, but with great info; perhaps you could use a few subheadings, and then use "Challenges" as a separate heading altogether, so it would be the 6th section, instead of nested as 5.1; placing Original Order, Appraisal and Provenance as nested subheadings- in order to make them more prominent, as I believe they are key to your wiki.
