Errata for Bott and Tu's book "Differential Forms in Algebraic Topology" My book is Differential Forms in Algebraic Topology by Loring W. Tu and Raoul Bott of which An Introduction to Manifolds by Tu is a prequel.
Is there a good list of errata for Bott and Tu available? A cursory Google search reveals not much except this: Some possible mistakes in Bott and Tu, and possibly more here though uncompiled. Is there any source available online which lists inaccuracies and gaps?

*Copying this: Errata for Atiyah-Macdonald

*Closed here: Errata for Bott Tu Differential Forms

*Even though I was suggested here: An old “list question” edited to include other points


*My recent question: How does one handle books without errata?

*I'm hoping something off-topic on stackexchange would be on topic on overflow.
 A: Here is the comment to this book in author's web page:


Differential Forms in Algebraic Topology (with Raoul Bott), third corrected printing, Graduate Text in Mathematics, Springer, New York, 1995.

The third printing published in 1995 corrects misprints in earlier printings; after that, the book has remained stable. Any printing dated 1995 or later should be fine. Earlier printings should be discarded.

Also you can check my web page for all possible math books errata (not completed yet).
A: In page 18 (proof of Example 1.6), they claim "there are no constant functions on R1 with compact support" when they should have said "there are no nonzero constant..." This is confirmed in this question.
A: In section 5, the closed Poincaré dual should be characterized with $\int_M \eta_S \wedge \omega $ and not $\int_M \omega \wedge \eta_S$.

*Confirmed here: Closed Poincaré dual, why $\int_M \omega \wedge \eta_S$ and not $\int_M \eta_S \wedge \omega $?
As for the implications on the compact Poincaré dual, I'm waiting for answers or comments here: Closed Poincaré dual is $\int_M \eta_S \wedge \omega $ and not $\int_M \omega \wedge \eta_S$. What about the compact Poincaré dual?
