Category:Old maps of Montreal

This category structure needs to be re-evaluated: Please provide a template to go with "xth century maps of Montral", "17X0s maps of Montreal" and only below that the individual years. Check out the structure of Quebec for an example.

Also, consider to dissolve single-year map categories of the city into decade-categories: There are 9 Files deserving to be together in "1720s maps of of Montreal" instead of being distributed over six supertiny categories. Enyavar (talk) 17:25, 30 August 2022 (UTC)

Or, better, put everything back in one single category and order it by year, so one can see at a glance how Montreal and maps of it developed.

This current structure that requires one to look at 60 categories to see that is a disaster. It helps nobody. The task of categories is to bring similar maps together (and maps of the whole of Montreal, even decades apart, have that similarity). The present structure splits similar things apart, and makes them impossible to view together.

Pinging @AnRo0002: , who appears to have created this abomination. Jheald (talk) 20:17, 30 August 2022 (UTC)

I'll look for it next week anro (talk) 20:20, 30 August 2022 (UTC)

Well, structures like this make sense with London and Paris etc, when there are 2823 old maps. Depending on how much stuff there is, my recommendation is first make century-categories, and if these overflow, go with decades. Enyavar (talk) 07:34, 31 August 2022 (UTC)

Yes, it's a classic case of excess fineness undermining the usefulness of the category tree. Someone started with "by year" which is too fine since most years have none and the average is fewer than five. One could start with "by century" but that's a bit coarse, so "by decade" will make it most usable. And in any case, do make a parental "by century" category.

Apparently almost nobody is watching this CfD. I'll take that as meaning I can make the decision myself. So, my plan for the first step is to create the decadal categories, patterned on Category:Architecture in Montreal by decade starting with the oldest. Not rushing; I only intend to finish it this month. After that, I'll return and seek possible discussion of which annual categories ought to be deleted and which ones kept. None of this will start today; I'll await comment or a day's silence before proceeding. Jim.henderson (talk) 18:07, 9 February 2023 (UTC)

support, please proceed. After this got done however, I will have to look for another "bad practice" example to explain what good practice ought to be. Enyavar (talk) 05:52, 10 February 2023 (UTC)
