Gaia Library

The https://www.kamen-rider-official.com/zukan/characters/2819 is a special location accessed by Philip. 
==Overview==
The Gaia Library is not a physical location per se, but rather a visual representation of Philip's vast knowledge of the all information known on Earth, representing as a pile of bookshelves, containing dozens of books, which each book represents an unique knowledge, including people, venue or a certain knowledge, etc. He is capable of accessing the library due to his nature as an avatar of the True Gaia Memory, allowing him to narrow down information regarding Gaia Memories and their concurrent users. 
To obtain the information he needs accurately, Philip needs a keyword provided by others to search for the information, usually by Shoutaro, sometimes Akiko or Ryu. Occasionally, Philip can also input the keyword by himself if he has the idea to do so. When the keyword was inputted, all the books unrelated will be disappeared, usually only a few books will be remain, after all the necessary keywords are input, the accurate book will reveal its name, and Philip can obtain the accurate information immediately by reading it. If the results cannot be simplify by the keywords, the books will remain, Philip can still choose to read all of them, albeit it will affect his effectiveness in case investigation. In some situation, the results of the book will be changed, as the situation to extract a Gaia Memory from human body will be "death", but the results will change to "alive" after the keyword "Accel" is input, which explains Accel is the only one who can safely extracts a Gaia Memory from human body by external means. 
According to Philip himself, the books only contains all the objective information of the Earth, but not the subjective ones like people's mind and feelings, as he explains to Ryu that he can read the tragic incident of his family's death at Isaka's hands, but he cannot read Ryu's personal feelings in the incident. 
Philip is also capable of connecting others to the library, as he has once connected Shoutaro to here through the usage of Fang Memory, though it is revealed that the library at that time is only the inner world of Philip. 
After Wakana Sonozaki has witnessed the True Gaia Memory, she is also able to access to the library, and later even able to use the library to touch the books and search for information herself, competing the ownership here. Wakana once gained the superior advantage here due to her able to sense the access from Philip and she can transform into Claydoll Dopant in the library, while Philip cannot do so. Though Philip later found the countermeasure by tuning down the synchro rate of himself. As the two explains, only people whose synchro rate reaches 100% can touch the books of the library and can be touched by others, while Philip has once tuning down his own synchro rate to 50% to make him being intangible in the library, while still able to access it at the lowest requirement. 
It seems that Ryubee Sonozaki has a limit control towards the library despite he cannot access the library himself, as he can limit Philip not able to search for the keywords related to him, including Gaia Memories, Foundation X, Museum, and the family members of Sonozaki, which includes Philip himself, causing not able to know about his own past after his amnesia. Though this limitation is later being removed by Wakana. 
Besides the external control and internal interference, there also exists some books which cannot be searched or access due to specific reason. For example, "Heaven's Tornado" is a book which has been locked, and can only be opened with the requirement of a special keyword, "wave". A special situation for Philip, the book "My family" is a book which all its pages are torn, which also affects him to search the books with the opening letter "F". Though Philip has overcome the situation after recognizing Shoutaro and Akiko has part of his family. With the images of the two covering over the torn pages of the book. 
It was later revealed that people with their identity hidden cannot be searched directly in the keyword, unless their real names were found, like Shroud, whose information was found only after her real name, Fumine Sonozaki was discovered.

==Notes==
*In the non-canonical film Kamen Rider Heisei Generations Forever, Woz was seen to somehow be able to access the Gaia Library through unknown means. According to producer Shin-ichiro Shirakura, Woz didn't actually access the library as it was all within his own imagination.https://twitter.com/cron204/status/1129386061623259136 This is later supported by the fact that Masaki Suda was originally invited to reprise his role as Philip in the film where his character was intended to access the library, but this was cut out due to Suda's unavailability.https://news.yahoo.co.jp/articles/23a46ced2e3dc3a80557460d0cebeca53dd9e057https://tokusatsunetwork.com/2018/12/masaki-suda-interested-in-appearing-in-heisei-generations-forever/
