# Put different title on the top of pages

I am writing a paper. Since, my title is too long, i need to write short title for top pages. For instance, this paper has a long title, but title of top pages are different. Does one help me ?

I have another question. How can one put a title from some page to other page, and then put another title from some page to end?

So here is a demo:

\usepackage{showkeys}
\floatplacement{figure}{H}
\usepackage[T1]{fontenc}
\usepackage{tikz}

\usepackage{scalefnt}
\usepackage{geometry}
\usepackage{pdflscape}
\usepackage{afterpage}
\usetikzlibrary{shapes.geometric}
\usetikzlibrary{decorations.pathmorphing}

\usepackage{hyperref}

• Welcome to TeX SX! We can help, but we need a minimal, compilable, (non)working example – Bernard Sep 7 at 12:17
• @Bernard : I don't know how i can make it like Tex form. – R R Sep 7 at 12:24
• @RR: Use \title[<shortened title>]{<long title>} to specify the shortened form of the title that will be displayed in the page headers. – leandriis Sep 7 at 12:33
• @RR: If the short title overlaps with the page number, your short title is still too long for the available space in the header. – leandriis Sep 7 at 12:54
• If you think you're doing your readers a service by creating two separate "short titles" -- the second being "applications to affine iterated function systems", right? -- in the header line of each page, I'm afraid your expectations regarding your readers' attention span are utterly unrealistic. From experience, I'd say that ca. 99% of readers do not play close attention the running headers, and these readers would be highly unlikely to notice the change in the "short title". Either use a single "short title" for the entire document or write two separate standalone documents. – Mico Sep 7 at 14:38

You need to choose a short title:

\usepackage{showkeys,lipsum} % remove for production version

\usepackage[heightrounded]{geometry}
%\usepackage{pdflscape}
%\usepackage{afterpage}
\usetikzlibrary{shapes.geometric}
\usetikzlibrary{decorations.pathmorphing}

%\floatplacement{figure}{H} % this is sure to ruin pagination

I added also a few modifications. Beware that \floatplacement{H} is a very dangerous thing to do, because it will most certainly make pagination impossible.

Also heightrounded for geometry is important, in order to avoid warnings on every page (the first page will always issue a warning with amsart.
