1. To make titles available we make use of so called marks leftmark and right mark which are available on all pages These can be set in macros using markboth for left mark 4 for right mark markright for right mark There is no separate markleft For the page building mechanism the content of the leftmark and rightmark is determined as follows leftmark contains the last for left mark issued before the end of the page while rightmark contains the first for right mark issued on the page If none have been issued on this page the most recently defined one from former pages will be used 1 The user may also use them manually in the text though this might annoy copy editors 2 Note that in some circumstances some confusion may arise concerning the content of the marks see 4 section 4 3 4 page 218 219 although the marks work without any problems in most normal chapter based documents To ease things all sectional macros have been equipped with a special macro named sectional macro mark e g sectionmark which will be given a title as an argument These sectional marking macros initially do nothing but they can be redefined to use markboth or markright REMARK Please recall that the sectional macros in EXT FX support up to two titles i e chapter for head and toc for text where for text will be used for all if for head and toc is missing In memoir we extend this even further

The next time I need to write a new document I can copy this one and start anew The new tricks I picked up are included and ready to be used again The downside is that each time you add a new technique to your usual document source it may take an hour or two or more If you like experimenting with LaTeX this is no problem But for those who want to spend their time writing rather than fiddling around with LaTeX the extra hour or two needed to figure out each new feature 1s prohibitive and you just do without A year or so ago The PracTex Journal received an article from an engineering Ph D student Lapo Mori While writing he must have found he was spending a lot of time researching LaTeX features Shortly after submitting his article he proposed that there should be a LaTeX pedia That is an online resource where an author can easily find useful information about LaTeX and examples of LaTeX documents Lapo proposed this project to his friends at the Italian Users Group GulT and it has become one of the group s long term goals I haven t spoken to Lapo recently and don t know the state of this project but it certainly seems like one that needs to happen sooner than later There are currently several good online LaTeX resources In my browser s bookmarks I ve collected about 100 such sites Each has its advantages and maybe a few shortcomings Still when I want to know about a package or feature I most often use a search engine and type

59. s In 1991 my son a photographer and I undertook a two week summer vacation project to study the marsh He took the 35mm photos and I was the photographers assistant We both did research about the marsh in the library of our local nature center We wrote a script and recorded it on cassette tape And on the second Saturday of our vacation after sunset when it was dark enough for the slides to show great colors we presented our slide show of the marsh to my wife manually changing the slides to follow the tape recorded narrative In the following years I presented the slide show on several occasions to small groups of guests in our home Eventually I got the idea that I should create a CD version of the slide show that I could give to people to watch on their own computers In about 2000 I paid Kodak to scan the 212 slides in our slide show and to give me a CD with high resolution digital versions of the slides In 2005 I finally got around to creating a CD of the slide show using basic HTML First I processed every digital slide with Photoshop to create cropped color adjusted low resolution jpg files of each slide suitable for computer screen dis play without taking up as much space as the scans from Kodak did Next I Copyright 2008 David Walden edited the Word file of the script of the slide show to a a driver file which could be processed with a Perl program see scorton marsh script txt on the HTML page for this column Notice th

64. tem files could be bundled together at a point in time and kept along with the document source files This would be one way to solve the problem of enduring documents There might be some technical issues with organizing file system directories so that a LaTeX system could process the document But if this problem could be solved it would provide a way to have enduring LaTeX documents One problem with this approach is that there would be a large cluster of files that could be used for one document only This would work well for a single author working on a single computer system However if the author wanted to share this document with a collaborator or send it to a publisher there could be problems The size of the file bundle would make this cumbersome and it could be difficult for the person receiving the file bundle to get it all to work One way to reduce the size of the file cluster is to distribute the set of LaTeX system files to an online archive Many current LaTeX systems fetch needed files from online archives If the set of needed LaTeX system file versions could be kept in an index a LaTeX system could use the index to fetch the needed files from an online archive This would reduce the size of the file cluster since authors could exchange just their source document files along with an index of LaTeX system files In any case it seems that the problem is one of ensuring that a unique set of files can be maintained so that a LaTeX docume

66. we re using Literate Programming to embed linguistic rules in a document We re actually using DocBook but we use dblatex to convert the DocBook document into LaTeX form and XeTeX to format that into a printable or displayable document One of the problems we ve encountered is that of long tables It seems to me that LaTeX is very good about formatting tables if you know in advance how much room the table is going to occupy on the page If you don t know that then you can wind up with a table that runs off the end of the page or tables that are split when they should have been floated depending on which table package you use There doesn t appear to be a single table package that handles both floating tables and tables that are longer than a single page In our case we can look at the final result and change the kind of DocBook table we use and as a result the kind of LaTeX table that dblatex gives us But that seems like it shouldn t be necessary there ought to be a table package that looks at the size of a formatted table and decides whether to leave it where it is float it or break it over a page or perhaps both float it and break it over pages This is surely not too hard for a computer to do although maybe it was too hard for most people s computers to do fifteen or so years ago when the table packages were written Even when we choose the right kind of table for a particular document later changes to the document or changes
