# Memex Device >[!Links]- >[[Second Brain]] >[[Blogging is essential to the development of a second brain]] In 1945 Vannevar Bush wrote a piece in *the Atlantic* called "How we may Think"[^1] which pondered on the development of a so-called 'Memex device': > *A memex is a device in which an individual stores all his books, records, and communications, and which is mechanized so that it may be consulted with exceeding speed and flexibility. It is an enlarged intimate supplement to his memory. > It consists of a desk, and while it can presumably be operated from a distance, it is primarily the piece of furniture at which he works... > Yet if the user inserted 5000 pages of material a day it would take him hundreds of years to fill the repository, so he can be profligate and enter material freely... > Books of all sorts, pictures, current periodicals, newspapers, are thus obtained and dropped into place. Business correspondence takes the same path.* This is the first mention of a [[Second Brain]]. It is also similar to the concept of a [[digital garden]]. ## Footnotes [^1]: https://www.w3.org/History/1945/vbush/vbush1.shtml
