Tomorrow's TeX Hour is a bit special. It's the fi= rst devoted to Experiments and Exploration. It's also the 20th TeX Hour= , and so a time to celebrate, look back and look forward.

The meeting is Thursday 29 April, 6:30 to 7:30pm UK time. The time = now in the UK is at https://www.google.com/search?q=3Duk+time. The zoom li= nk for the meeting is

The TeX Hour has a monthly cycle for its topics.

Fi= rst Thursday: Beginners
Second Thursday: Accessibility
Third Thursday= : Conversion (eg LaTeX to PDF, LaTeX to HTML, markdown to LaTeX)
Fourth = Thursday: Durable Documents (same outputs give same input across space and = time)
Fifth Thursday: Experiments and Exploration.

After tomorrow, the next E+E TeX Hour is Thursday 29 July, which is= just before the online TeX 2021 conference https://tug.org/tug2021/. At tomorrow's TeX= hour I'd like us to take a 3-month before and after view of the TeX Ho= ur, with an eye on presentations at the TeX conference. I'm also lookin= g to curate our growing library of video records.

= As usual in TeX Hours, all are welcome. Looking forward, next month we focu= s on Bibtex and reference management.

On Thursday = 6 May we're pleased to welcome Patrick Daly, author of the widely used = natbib package. He'll give us the history of natbib, and answer questio= ns. The focus will be on the Beginner experience. We hope later in the mont= h to have a more technical reference management TeX Hour, either as Convers= ion or Durable Documents.
