According to ESOhead (http://esohead.com/books) there are 2,233 texts and the vast majority are not duplicates. If a location col is used, it should only be the location name and that's all - no lengthy directions. I can maybe see this being of use if someone sorts by location to see all the books for the area that they are currently in - but you need to be careful with the accuracy of info here. These need to be guaranteed locations and not possible bookshelf spawns.
Descriptions are useful for people casually browsing the table looking for new lore info, for example. The title's are not always explicit.
