A couple of them mention menstruation, which also scares the bejesus out of some folks.

Behold, you are beautiful, my love,
behold, you are beautiful!
Your eyes are doves
behind your veil.

Your hair is like a flock of goats
leaping down the slopes of Gilead.
Your teeth are like a flock of shorn ewes
that have come up from the washing,
all of which bear twins,
and not one among them has lost its young.

Your lips are like a scarlet thread,
and your mouth is lovely.
Your cheeks are like halves of a pomegranate
behind your veil.

Your neck is like the tower of David,
built in rows of stone;[a]
on it hang a thousand shields,
all of them shields of warriors.

Your two breasts are like two fawns,
twins of a gazelle,
that graze among the lilies.

Until the day breathes
and the shadows flee,
I will go away to the mountain of myrrh
and the hill of frankincense.

You are altogether beautiful, my love;
there is no flaw in you.

Come with me from Lebanon, my bride;
come with me from Lebanon.
Depart from the peak of Amana,
from the peak of Senir and Hermon,
from the dens of lions,
from the mountains of leopards.

You have captivated my heart, my sister, my bride;
you have captivated my heart with one glance of your eyes,
with one jewel of your necklace.

How beautiful is your love, my sister, my bride!
How much better is your love than wine,
and the fragrance of your oils than any spice!

Your lips drip nectar, my bride;
honey and milk are under your tongue;
the fragrance of your garments is like the fragrance of Lebanon.

A garden locked is my sister, my bride,
a spring locked, a fountain sealed.

Your shoots are an orchard of pomegranates
with all choicest fruits,
henna with nard,
nard and saffron, calamus and cinnamon,
with all trees of frankincense,
myrrh and aloes,
with all choice spices-
a garden fountain, a well of living water,
and flowing streams from Lebanon.

Awake, O north wind,
and come, O south wind!
Blow upon my garden,
let its spices flow.

County board bans `Invisible Man' from school libraries

RAMSEUR - "Invisible Man" by Ralph Ellison is banned from the shelves of Randolph County Schools libraries.

By a 5-2 margin, the Randolph County Board of Education voted Monday night, at its regular meeting held at Eastern Randolph High School, to remove all copies of the book from school libraries.

...

The book, originally published in 1952, addresses many of the social and intellectual issues facing African-Americans in the first half of the 20th century.

It was one of three books from which rising Randleman High School juniors could choose for summer reading for the 2013-14 school year. The others on the list were "Black Like Me" by John Howard Griffin and "Passing" by Nella Larsen; honors students had to choose two books.

There was little discussion after the board was presented with the Central Services Committee recommendation concerning the parent's complaint about the book. All board members had been supplied with copies of the book last month to read.

McDonald asked if everyone had read the book, stating, "It was a hard read."

Mason said, "I didn't find any literary value." He also objected to the language in the book. "I'm for not allowing it to be available."

Invisible Man won the U.S. National Book Award for Fiction in 1953. In 1998, the Modern Library ranked Invisible Man nineteenth on its list of the 100 best English-language novels of the 20th century. Time magazine included the novel in its TIME 100 Best English-language Novels from 1923 to 2005.

On Wednesday evening, the Randolph County school board in North Carolina 6 to 1 to retract its ban on Ralph Ellison's Invisible Man at school libraries. In the days after the board took the classic novel about race and identity off library shelves in response to a parent complaint, the decision has drawn fierce criticism and national scrutiny. Vintage, the book's publisher, donated copies to a nearby bookstore to be given away for free to students, and waiting lists for the book grew at local libraries and bookstores. Board member Gary Cook told the Los Angeles Times, "We may have been hammered on this and we may have made a mistake, but at least we're big enough to admit it."

...in an age of Smart Phones and Kindle's isn't it becoming kind of hard to ban books?

A reason to preserve the physical book that has been digitized is that it is the authentic and original version that can be used as a reference in the future. If there is ever a controversy about the digital version, the original can be examined.
