The best way I can think of is that when you want a clean library, either on PC or mobile app, type in rating:>=0 ANDNOT perseus. or, after doing this, select all resources displayed by pressing CTRL+A, and tag everything with something like "nper" (stands for Non-Perseus). Then when you get overwhelmed with perseus in the future all you have to do is type in "nper" to limit your library.

Yes. At least it does on my Ipod Touch.

cool never knew that

I have ordered only those resources which I feel will add to my Bible study library.  I have passed on the others.

Me too.  As tempting as it is to have American Civil War documents on Logos, I have opted to keep my Library pure. [:)]

I signed up for all of it. You never know what gems will be in there. For instance, there could be good illustration in the Civil war stuff for passages dealing with slavery. It can help to compare the slavery of Paul's day with the slavery most familiar to us. e.g.

"In the neighborhood in which I lived was an old and much respected
clergyman who was called upon to preach a sermon on a day of some
national significance.
He made it the occasion for a florid panegyric upon American
institutions, which, he declared, assured freedom to all men. Here he
paused, “When I spoke of all men enjoying freedom under our flag,” he
resumed, “I did not, of course, include the Ethiopians whom Providence has brought to our shores for their own good as well as ours.
They are slaves by a divine decree.
As descendants of Ham, they are under a curse that makes them the servants of their more fortunate white brethren.”
Having thus put himself right on the record, he proceeded with his sermon.
No one seemed to take exception to what he said.

In the same neighborhood was a young preacher who had shortly before come into it from somewhere farther North.
In the course of one of his regular services he offered up a prayer in which he expressed the hope that the good Lord
would find a way to break the bands of all who were in bondage.
That smacked of Abolitionism and at once there was a commotion.
The minister was asked to explain.
This he declined to do, saying that his petition was a matter between
him and his God, and he denied the right of others to question him. That
only increased the opposition, and in a short time the spunky young man
was compelled to resign his charge.

About that time there appeared a lecturer on slavery — which meant
against slavery — who carried credentials showing that he was a
clergyman in good standing in one of the leading Protestant
denominations.
In our village was a church of that persuasion, whose pastor was not an
Abolitionist.
As in duty bound, the visiting brother called on his local
fellow-laborer, and informed him that on the following day, which
happened to be Sunday, he would be pleased to attend service at his
church.
On the morrow he was on hand and occupied a seat directly in front of
the pulpit; but, notwithstanding his conspicuousness, the home minister,
who should, out of courtesy, have invited him to a seat in the pulpit,
if to no other part in the services, never saw him. He looked completely
over his head, keeping his eyes, all through the exercises, fixed upon
the back pews, which happened, on that occasion, to be chiefly unoccupied.

Such incidents, of themselves, were of no great importance.
Their significance was in the fact that they all occurred on the soil of a free State.
They showed the state of feeling that then and there existed.

So, I wonder what happens with the Kindle Fire - with only 8GB of space and let's say, 3,000 books with the Perseus collection...does it download all of it?  Amazon says 8,000 books will fit on 8GB, but I think many Logos books...well, they will take up more space than the typical "book".  Anyone have thoughts?  Can you choose to delete or not download onto your mobile device certain books?
