### Bob on TAC

#### Posted by Tom Leinster

Every month, the *Notices of the American Mathematical Society* carries a piece on mathematics publishing: journals, parasitic publishers, and the like. This month, it’s by Bob Rosebrugh, founder and managing editor of *Theory and Applications of Categories* (TAC).

Bob’s piece relates how TAC was set up, and why, despite TAC being one of the first electronic mathematics journals, he wishes he’d followed his gut feeling and done it even earlier. He briefly mentions TAC’s sister publication, *Reprints in Theory and Applications of Categories*, which seems to me to represent an idea that should have caught on much more widely.

But most of all, he urges action —

So, if your subject area of mathematics doesn’t yet have a free electronic journal,

it’s time to start!

— and tells us that it’s actually much less work than you think:

## Re: Bob on TAC

I hope this helps get TAC into the bean counters’ books. Famously, TAC is not indexed by the usual companies, so that citations don’t count and it has no impact factor, which, while I don’t believe in impact factors, lacking one looks dodgy.
