5. Acknowledgements and Related Resources

Substantial portions of this document, notably the bits on maintaining your UPS, were originally part of the apcupsd documentation. The project maintainers have graciously permitted me to re-use them here. Other parts were part of my Unix Hardware Buyer HOWTO.

There was a previous UPS HOWTO by Harvey J. Stein, last updated in 1997. It was so out of date that I ended up using none of it.

There is UPS FAQ which is slightly dated but still contains some good advice.
