Back in the day I charted the authors who'd written multiple Desert Isle Keepers. I thought it might be fun to change it slightly. This new chart includes all authors with at least one DIK, and if they have [only] one DIK, they must also have two B+ reads. I may also do another chart of the next rung "down"—one DIK and [just] one B+/multiple B's (think Madeline Hunter), or authors with lots of B range grades (such as MaryJanice Davidson or Calvin Trillin), mostly at the upper end (like Anne Rivers Siddons). I'm also considering a chart of authors with the widest variation of grades, like Catherine Coulter, who has lots of DIKs, but also many D's/F's.
In the chart that follows, if you see this color, it refers to an addition over the original chart, and includes individual books, authors, and the entire "B+" column.
BTW, Goodreads and my tags at Goodreads made this an easy task as I have a tag for Desert Isle Keepers, and separate my B+'s from other B's by star (4=B+, 3=B/B-)
