Eiro stepped up to the large, ornate double door that had appeared on the far side of his mental library. It was weird; the library didn't usually change in this way. Of course, there were parts of it that were simply altered subconsciously; like the improvement of the quality of the space that happened just now. Since Eiro's mental capacity itself had improved vastly, it made sense that not only the books but the library itself improved in quality as well. And of course, new memories that formed would automatically be added onto the shelves, and the library would adjust and shift around depending on how many memories Eiro's mind actually held.
