The Logo Tree peoject has two major goals: (1) to collect information about current and past Logos; and (2) to build a genealogical tree of Logo evolution. This tree is an evidence of the extreme diversity and vitality of Logo as a programming language.

In 2002 we started to harvest basic information about Logo. This was done in various ways: searching the web, talking with people, monitoring forums and sites about vintage software. Today the tree lists Logos developed for the last 40+ years. We were helped by people all over the world.

If you are interested in the Logo Tree and have questions or proposals, send an email to boytchkev@fmik.uni-sofia.bg after deleting both letters k from the address.
