To document as many occurrences of bi-grams found accidentally.
Starting with S and B, after the Silver Bullet project (1990-1991) this website intends to collect and define word pairs.
Dictionaries tell you the meaning of single words.. and some of the better ones give you instances of their usage. This bi-gram site will attempt to do something similar for two words.
Eventually there may be a sub-domain for each pair of letters. e.g. sb.bigram.co.uk
