Today (27th July 2020) the Alfred Russel Wallace Correspondence Project (WCP) has reached a significant milestone, and in doing so has made an important contribution to Wallace scholarship. The milestone in question is that the project has finally finished transcribing ALL of Wallace's surviving correspondence (5,680 letters, of which 2749 are from him, 2153 to him and 778 are third party letters), thereby unlocking the information they contain by allowing them to be more easily read and information in them discovered using electronic searches for words and phrases.
