This is a decent example of plain writing used in a library policy manual.

I ran the section through Microsoft Word to test it. It scored:

• 95% on the casual writing level

• 3.6 sentences per paragraph

• 15.2 words per sentence

• 39.5 on the Flesch Reading Ease scale

• 11.4 on the Flesh-Kincaid Grade Level scale

• 43.4% Passive Sentences

This tells me that I would focus on using active voice, simplifying some of the sentence structures, choosing simpler words, and shortening my sentences overall.
