# How to abbreviate a thesis title on the top of each page

My thesis title is very long (two lines). LaTeX outputs it ok on the title page, but smashes the whole title together into a single line on subsequent pages, as sort of an automatic heading which bleeds into the margins. What command do I use to include an abbreviated title (i.e. the part before the colon)?

FOR EXAMPLE: If the main title is

This is the first half of my title: this is the second half followed by a colon.


The automatic title heading on subsequent pages should be

This is the first half of my title.


I am using \documentclass[11pt]{amsart}. I am also substituting amsart with amsproc and amsbook. The result is the same for all three cases. What should I do?

MWE

\documentclass[twoside,onecolumn,11pt,reqno, a4paper]{amsart}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{amssymb}
\usepackage{mathrsfs}
\usepackage{graphicx}
\usepackage{microtype}
\usepackage[color]{showkeys}
\usepackage{mathptmx}
\usepackage[T1]{fontenc}

\title{Super Long Long Long Long Long Long Long Long Long Long Long Long Long Long Long Long Long Long Long Long Title}

Welcome to TeX.SX! Please add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. –  Jubobs Oct 27 '13 at 19:49

Please do not post your code as comment. Instead, edit your question to add your code there. Also, make sure it's compilable, beginning with \documentclass{...} and ending with \end{document}. Only load the packages that are relevant. –  Jubobs Oct 27 '13 at 20:03

Add the new command \shortitle in this way:

\documentclass[twoside,onecolumn,11pt,reqno, a4paper]{amsart}

\usepackage{fancyhdr}
\usepackage{lipsum}% dummy text

\newcommand\shortitle{This is the first half of my title}

\title{\MakeUppercase{\shortitle}: this is the second half followed by a colon.}

\fancyhf{}
