For sometime I have used the very useful MathSciNet MRef tool. It allows one to input a citation (e.g. from zbMath or from MRLookup, if you don't have MathSciNet access, as I didn't for a while, and still don't conveniently when out of the office) and obtain canonically formatted citations in a variety of formats.
I'm not a big user of BiBTeX (maybe I should be) and so I appreciated MRef's ability to output canonically formatted TeX code which I could paste into a manual
thebibliography environment in LaTeX. However, since MRef was redesigned, it simply says "TeX format is temporarily unavailable."
Does anyone have some insider knowledge as to when TeX formatting might return?
Are there any other (free) tools which do a similar thing?
(I know I should have a better bibliography management system, but as I get older, I discover that time is my limiting factor in many things, and so it's nice to just have a simple system which adequately works, which MRef used to...)
