Completing the True Guertena Exhibit: Checking paintings gets them into the true Guertena exhibit (you have to be able to read the full name, though, so if the name contains words that Ib doesn't know, you have to have Garry with you to read them to Ib or it won't count). Some paintings, however, require that you read books (by examining bookshelves). Ones that contain unknown words will require Garry's assistance, obviously. To get Garry, Mary, and Ib's mother and father into the exhibit as well, get the four "good" endings (where Ib escapes through the Fabricated World painting). It doesn't matter if you get an ending before unlocking the true Guertena exhibit; as long as it's on the same file (continued through new game plus(es)), it will count.
