Well if you've got a copy of The Traveller Periodical Bibliography, you'll see the kind of thing I'm after, but here goes:

Title - as given at the top of the article but I'd be interested to know if a contents page lists it differently.  For full marks I'd like the original capitalisation and rendering (e.g. "and" or "&")

Author - as given at the top/end of the article for preference, but from the contents page (or possibly cover) if need be.  If there's no author I'd be interested in the editor's name, as certainly for fanzines, they're normally the ones to credit.

Journal title and volume/issue number (For full marks note any 'design' styling such as the German magazine 'AdventurePunkt' which has a 'point' instead of the word - there's an English one that does something similar but it's just not coming to mind at present)

PDF or print or both?  Online?   (I'm pretty sure you're talking about a printed magazine, but I'll put this in for completeness sake)   (for 'online', it does have to have some form of 'magazine' output - I'd  love to do all Traveller websites and blogs, but there has to be a limit...)  (Freelance Traveller is a good example of PDF and online - with the latter having a one issue embargo, Stellar Reaches is a good example of print and PDF).

Year of publication and month/season of publication (or any other way it's differentiated)

The page number of the first page of the article (in square brackets if it's not actually on the page and you're counting from a nearby page).

The page number of the last page of the article (in square brackets if it's not actually on the page and you're counting from a nearby page).

The number of pages the article covers e.g. an article from pages 3-6 and continued on page 24 would be 5 pages - think of it as the number of pages you'd have to print.  Doesn't matter if there's a half page of advertising etc.

Is the cover of the magazine anything to do with the article?  *might* it be?  Is the article mentioned as 'featured' or anything?
Page size of the journal?  US Letter, A4, A5, digest sized?  Actual measurements if it's very non-standard.  (Ideally in inches and cm)

OK, those are the easy bits.  (I told you, you might regret this!)  We go on:

Collation: are there:

maps (1 or more than 1?) - not including deck plans

tables - including blank forms (what are the names/numbers of the forms?)

diagrams - including deck/building plans - are the latter colour or isometric?

illustrations

glossary - not including Library Data

bibliography - not including invented bibliographies (roughly what does it cover?  'novels the article was inspired by', 'non-fiction references for further reading'?)

index - unlikely in a magazine article but there are some (e.g. Freelance Traveller)

Contents - a general outline of any notable features in the article.  If there's a map, what does it cover?  (ignore less than world scale maps - I'm looking for planetary maps, subsector maps, sector maps etc)  If a world is detailed what is it's name, sector, UWP?  If a ship is detailed what is its name, type (name/number) and tonnage?  If it's an adventure and has titled scenarios of more than a couple of pages, what are they called? (and where is the adventure set?  For how many PCs?  Briefly what does it involve?) Are there equipment sheets for anything?   (I'm not currently listing minor NPCs - although I have thought about it - but if they're a major part of the article what are their name(s) and UPP?  Any timelines?

Department - is the article part of a regular 'department' in the magazine?

Era - is it obvious what era the article is from or what rule-set it's being written for?

Comments - these might range from a comment on the contents, a note of anything an editorial says about the article, how the article relates to other Traveller books/articles on the same subject, or other known details about the article perhaps from an interview with the author or that it was an adventure played at GenCon or whatever.

(yes, this part of the entry is tough to do!)

(but it may be so straightforward or so short a piece it doesn't warrant any comment at all)

I think that's everything - I quite understand if you take one look at this and decide you'd rather not bother.  It looks like a lot to wade through but I can assure that after some years and 2 or 3 thousand articles you can do it quite quickly.... :-)

For those interested, I'm working on the 2nd volume of Periodical Bibliography and it's something like 100 pages already although far from finished (and not yet in two columns which shrinks it).  If anyone would like to help out, you'd be more than welcome if the above hasn't put you off.  Some sources - such as Freelance Traveller - are available on the web so you don't have to have a big collection of obscure stuff to contribute!

(and yes, I'm still badgering Andy Lilly, poor chap, for the 3rd edition book bibliography to come out asap).

Hope this helps.  I'll credit you as "Tom Rux" if you're not there already - let me know if you want a pseudonym or more complete name.
