With this spell, the wizard may detect whether or not a book or scroll is cursed, what language it is in, whether or not its contents are encoded or enciphered, and other general information about its contents.
None of the following things will be revealed by the spell, though:
1.	Absolutely nothing will be told about the special books listed in the Dungeon Master's Guide (a libram of ineffable damnation, a manual of puissant skill at arms, etc.). Likewise, very powerful books (artifacts or relics) will be utterly out of this spell's power.
2.	Specific spells and scrolls will not be revealed ("secret page spell on page 2", "fire trap cast on cover", "explosive runes on binding", etc.), nor will the exact nature of a curse, if present, be told.
3.	If the book or scroll contains spells, the wizard will not be told precisely which spells are there, although the DM might allow weak statements like "20 pages are devoted to spells", or "a few weak spells seem to be inside this tome".
The reverse of this spell, tome shield (abjuration), must be cast on a particular book or scroll, which is thenceforth immune to Dheryth's tomelore for one month. It further resists the operation of the history and identify spells, granting the protected book a saving throw versus spell as if it were a wizard of the same level as the one who cast tome shield.
The material component for this spell is a magnifying glass, for the reverse it is a blank page. Both are consumed in the casting.
