It is the general policy here at Hogewash! to credit sources of information used on the blog. There are some exceptions.
First, some sources wish to remain anonymous. Unconfirmed anonymous sources are identified as unconfirmed.
Second, if something is general knowledge or has been talked/written about extensively, it is assumed that no sourcing is required.
Third, working independently, I may post something that is similar to someone else’s previous work. If I’m unaware of someone else’s work, I can’t cite it.
Fourth, I screw up sometimes. If a demonstrable error is brought to my attention, I will correct it.
