Organising all my contacts
Rather than relying on notebooks, I have gathered all my contacts into a spreadsheet to keep organised. Looking for email addresses (hidden for privacy purposed for this screenshot) has unearthed a lot of other people to contact.
This is proving most helpful, and I can filter contacts by what I would like to approach them for. For example, Gerry Leonidas will be great for giving me typographic history advice but not so much for local community help!
