Either buy them back, or go to the Lake Arrius Caverns where the dagon shrine is, and look around in there. I have all the books (actually i have about 150 copies of each) but I found 3 books, 1 2 3, sitting ride beside each other.
After Baurus meets the Mythic Dawn, and you are up on the bridge sniping them, go straight across from there to another room where the agents have been staying. There are a couple of beds, chests with nice items, and some Mythic Dawn clothing and several Commentaries.
in bruma go to jearls house she is currently on holiday but she works with the mythic dawn she's got the commentaries 1 & 2. when you get in the house there will be a table moved to the side and a trapdoor showing go down it and into the basement and i think the books are in a chest or on shelf. and also there is another door in the basement that connects to a cave but all you''l find in it will be rats and crates and i think a chest. but remember this i'm currently on oblivion a necromancer scouring the lands of cyrodiil in secret searching for a way into the mythic Dawn Cult without doing storyline but i've only found jearls place who has them i don't know if she has came back from holiday yet though lol. she's a mythic dawn spy by the way i found a plan from the mythic dawn telling jearl to set up an oblivion gate infront of bruma lol but i'm gonna get out of bruma before it happens lol. and one more thing if you find mythic dawn commentaries 3 & 4 without storyline plz type in how to in like a site with questions about this. hope you find my info useful thx.
There is a way to get it all back. I never did it so I'll just give you a URL for a walkthrough. I always left all of my stuff at a house or something, but anyway here's that URL. http://www.uesp.net/wiki/Oblivion:Dagon_Shrine This is an extremley helpful site by the way. It helped me a lot in this game.

Get enough money to buy it back
You will get it back near the end of the main questline.
go to documents go to my games go to oblivion go to saves
unfortunately it never comes back after you steal it.
It will be printed on the back of the manual, or on the inside of the DVD case.
If you accidentally wrote on the back of a check, you should not try to correct it yourself. Instead, write "void" on the back of the check and request a new one from the issuer.
It can bring back things that you have accidentally deleted.
You cannot. Sorry.
