Dear Portal friends: Do you enjoy having history at your fingertips? We’ve appreciated your support over the years, and need your help to keep history alive. Here’s the deal: we’ve received a Challenge Grant from the National Endowment for the Humanities. Now it’s time to keep our word and raise matching funds for the Cathy Nelson Hartman Portal to Texas History Endowment. If even half the people who use the Portal this month give $5, we’d meet our $1.5 million goal immediately! All donations are tax-deductible and support Texas history: yesterday, today, and tomorrow.
