How do I get my acronyms out of the main glossary?

Question

I am writing my thesis and I must have a list of the abbreviations used. I'm using the acronym part of the glossaries package in LaTeX, and all went fine, until the number of acronyms broke, I think, 30, and then the extra ones went away. I tried deleting all of the files except the .tex file, and that got rid of the entire list of abbreviations. Upon further inspection, I found that all of my acronyms were being deposited in the main glossary instead of the acronyms list. So, my question is: How do I get my acronyms back into the acronyms glossary. Here's an example of what I am doing

%\usepackage{variousPackages}
\usepackage[toc]{glossaries}
\newglossary[alg]{acronym}{acr}{acn}{Glossary of Abbreviations Used}
\makeglossaries

\begin{document}
\newacronym{th}{th}{this}
\newacronym{ta}{ta}{that}
\printglossary[type=acronym]
%rest of the document
\gls{th}
\gls{ta}
%the rest of the rest of the document
\end{document}

If I tell LaTex to just print all of the glossaries, it will print the main glossary with the list of abbreviations. If I use the above code, it prints no abbreviations. The \gls commands still work. The list of acronyms simply doesn't show up unless I allow LaTeX to print the main glossary.

I have tried recompiling the code many times and using a makeglossaries perl script mentioned in another question on something similar, but so far, nothing has worked. Any help would be greatly appreciated.

I am working with the latest verison of MikTex, and WinEdt 9.0, for Windows. This seems like it might be something obvious, so I apologize if this has an obvious answer, but I can't seem to figure it out.

Again, thank you for any help you can give

Answer 1

\newacronym sets type=\acronymtype unless overridden in the optional argument. The default value of \acronymtype is \glsdefaulttype (usually the main glossary) unless the acronym package option is used, in which case \acronymtype is set to acronym. Since you're manually defining the acronym glossary using \newglossary, the acronyms are put in the main glossary. So you have the following options:

1. Manually set the type in the optional argument of \newacronym.
2. Redefine \acronymtype to the label of your custom glossary.
3. Use the acronym package option and set the title with the title key in \printglossary (or change the fixed name).

The other side-issue is that, as recommended in the manual, definitions are best made in the preamble (before \begin{document}).
