Now that DD is not a source of personal information about Tom Riddle 
as a student, who is there that Harry can find any information from?

If Harry is to find any clues from that time of LV's life, who are his 
resources?

Slughorn was his teacher of Potions, apart from having Tom as a 
regular in his Slug Club. Slughorn is also the new Head of *Slytherin 
House. 

Hagrid was at Hogwarts when Tom was there - and victomised because of 
it. Hagrid also know the scariest area around Hogwarts if Tom like 
scary places to go with **Horcrux hiding places. Hagrid knows the 
forrest, the first place we met LV in PS/SS.

The ghosts know a few things about Hogwarts and the  more notable 
students. Prof Binns, the ghost that teaches history and Nearly 
Headless Nick are on good speaking terms with Harry. But it's the 
Bloody Baron I think is hiding the most secrets - but how to get him 
to speak?

Moaning Myrtle is a ghost that deserves her own mention. She has been 
on good terms with Harry for some time. She owes her demise to Tom 
Riddle that was a few years ahead of her. She even lent Draco a 
shoulder to cry on as he prepared for DD's demise. She should know a 
few things .... if Harry can flatter her.

Another source of information JKR hid until the last book was Snape's 
mother, Prince. Huh, you ask? Lupin got Harry to look up the 
publishing date of the potions book and it shows that Prince was at 
Hogwarts at the same time as Tom Riddle. I am wondering how many of 
those darker spells may have been borrowed from Tom Riddle himself. If 
this young girl showed such promise in potions, she would stand out in 
the Slytherin Common Room. Did Snapes mother know Tom? Harry need only 
open the potions book again to find more valuable information.

FOOTNOTE:
(*The Slytherin Common Room may be very handy since Hogwarts shaped 
Tom so much. I was wondering how he "happened" to find the enterance 
to the COS in an active girls bathroom unless a clue was found in a 
place such as the Slytherin Common Room. Slughorn may allow Harry to 
look around and gather more clues.)

**The other Horcruxes were in places Tom had life changing 
experiences. The Cave complete with the thing he was most scared of - 
dead bodys, where he terrorised 2 other orphans. His Grandfather's 
house, where he schemed his first murder and framed another innocent 
(as he framed Hagrid). Could the Chamber of Secrets hold more secrets, 
like a Horcrux?
